Article: For things that grow, whether in height or weight, you can measure the rate of growth by finding the change in whatever quality you wish to measure, divided by the time. This formula can be expressed mathematically as:   rate=ΔhΔt{\displaystyle {\text{rate}}={\frac {\Delta h}{\Delta t}}} or ΔwΔt{\displaystyle {\frac {\Delta w}{\Delta t}}}  In these two examples, h{\displaystyle h} represents the height and w{\displaystyle w} represents weight. In both of these, t{\displaystyle t} is for the elapsed time. Some plants, like the Asian bamboo, grow very fast, with visible differences taking place within hours. For measuring something like the growth rate of a child, changes may not take place for months or a year or more. You need to select a time period that is relevant for what you are measuring.  Suppose an elementary class plants bean seeds and begins measuring their growth as soon as the first sprout appears. A reasonable time measurement might be about a month, measured in days. Scientists raising an orphaned baby elephant wanted to measure its growth rate over the first 90 days of its life. Measuring a growth rate requires that you set some starting point and measure the size at that time.  For the example of the students' bean plants, they chose the starting point to be the day that the first sprout appeared. The height at the point is set at 0 cm. For the baby elephant, veterinarians measured the elephant's weight the day it was born. Its initial weight on that day was 200 pounds. After the time elapses for your study, measure the height or weight of the object whose growth you are studying.  For the bean plants, the average height of the students' plants on the 30th day was 24 inches tall. Because the plants began at a height of 0, the amount of growth was 24 inches. For the elephant, after the 90 day study period, the veterinarians measured its weight to be 400 pounds. Enter the data that you measured into the formula and perform the calculations to find the growth rate.  For the students' bean example, the calculation will look like this: rate=24 inches30 days=0.8 inches day{\displaystyle {\text{rate}}={\frac {24{\text{ inches}}}{30{\text{ days}}}}=0.8{\frac {\text{ inches}}{\text{ day}}}}  For the elephant's growth rate, you must calculate the amount of change in the weight in the numerator as part of the calculation:  rate=400−200 pounds90 days{\displaystyle {\text{rate}}={\frac {400-200{\text{ pounds}}}{90{\text{ days}}}}} rate=200 pounds90 days{\displaystyle {\text{rate}}={\frac {200{\text{ pounds}}}{90{\text{ days}}}}} rate=2.22poundsday{\displaystyle {\text{rate}}=2.22{\frac {\text{pounds}}{\text{day}}}}
Question: What is a summary of what this article is about?
Understand the formula for measuring average growth rates. Decide how long you wish to measure the growth rate. Calculate the starting size. Measure the ending height or weight. Use the growth rate formula for either height or weight.

Problem: Article: Losing weight means burning more calories than you consume. Losing 5 pounds in one week translates to 17,500 calories lost.  A combination of cardio and resistance training (weightlifting) leads to higher weight loss than either activity alone. But if you must choose one, those doing only cardio lose more than those doing only resistance training.  Consider High Intensity Interval Training (HIIT). That's when you alternate between going all out and taking it easy. For example, you'd run in a dead sprint for 30 seconds followed by 60 seconds of jogging. This shortens your routine and burns more fat, believe it or not. In addition, when you're chilling on the couch, your metabolism stays high and you'll be burning more calories up to 24 hours later.HIIT is great for those with hectic lives — it only takes about 15 minutes. Just remember you still need to warm up and cool down. Stress is a huge cause of overeating. 60 minutes of yoga (done in the comfort of your living room during your favorite show) burns 180 – 360 calories — but that's not all. Studies have shown that practicing yoga leads to a number of benefits:  Reduced stress Increased body awareness (specifically hunger and satiety) Mindful eating Switching up your routine will keep you from plateauing and keep your body from getting used to your workout.  Varying your routine will help you stay motivated, a huge factor in success. Turn social events into opportunities for calorie burning. Skip the movies and go for frisbee golf, tennis, or swimming. Any activity can turn into exercise with the right mindset.  Opt for the stairs instead of the elevator. Use this as a reason to do chores. Do the gardening, wash your car — stay active! Walk or ride a bike to work or school. This also reduces your expenses and helps the environment, too! You may not see results immediately. Be patient.  As your body gets accustomed to the work out, kick it up a notch. Challenge yourself. Only do as much as you can handle. If you feel dizzy or faint, stop.
Summary: Develop an exercise plan. Take up yoga. Keep it fun. Find small opportunities. Stick to it.

Turkey drumsticks require almost an hour on the grill, and it's important to maintain a steady heat of about 300 °F (149 °C) so they don't burn or end up undercooked. Use a grill thermometer to test the heat of your grill. Sprinkle the meat all over with salt and pepper. If you want to add spices and other seasonings, spread mixed spices all over each drumstick to coat the skin. Try these delicious combinations:  For hot and spicy drumsticks: combine 1/2 teaspoon (1 g) cayenne pepper, 1/2 teaspoon (1.5 g) garlic powder, 1/2 teaspoon (1 g) black pepper, and 1/2 teaspoon (3 g) salt For herb-encrusted drumsticks: combine 1/2 teaspoon (.4 g) dried basil, 1/2 teaspoon (.7 g) dried thyme, 1/2 teaspoon (1.5 g) garlic powder, and 1/2 teaspoon (3 g) salt Lay them on a part of the grill that isn't getting a stream of direct heat, since this will cook them too quickly. This will ensure they cook evenly on all sides. Keep going as each side turns golden brown and crispy. Insert a meat thermometer into the thickest part of the meat. The drumsticks are ready when the internal temperature reaches 180 °F (82 °C).

Heat your gas or charcoal grill to medium heat. Season your turkey drumsticks. Cook the drumsticks in indirect heat for 1 hour. Turn the drumsticks every 10 minutes. Test the internal temperature of the drumsticks.
