If a person weighing 150 lbs. jogs at a rate of 5 1/2 mi/h burns 740 Cal/h how many calories do they burn running 3 1/2 h in a week?
Calories/mile is
(540 Cal/h)/(5.5 miles/h)
= 98.2 Cal/mile
The distance run in 3.5 hours is
5.5 mi/h * 3.5 h = 19.8 mi
Total Cal = 98.2 Cal/mile * 19.8 mile = __?
I am assuming that 3.5 hours is spent running in one week, not per day for a week.
Hi drwls it is not 540 Cal/h it is 740 Cal/h. thanks anyway!
Whoops! Anyway that is the way to get the answer. Keeping track of the dimensions, and multiplying and dividing them along with the numbers, helps a lot.
Thanks for correcting my error.
To find out how many calories a person would burn running for a certain amount of time in a week, we need to multiply the number of hours spent running by the rate of calories burned per hour.
Given:
- Weight of the person = 150 lbs.
- Jogging rate = 5 1/2 mi/h
- Calories burned per hour = 740 Cal/h
- Time spent running in a week = 3 1/2 hours
First, let's convert the weight from pounds to kilograms because most calorie burn calculations are based on weight in kilograms.
1 pound (lb) is approximately equal to 0.4536 kilograms (kg).
Therefore, 150 lbs = 150 * 0.4536 kg ≈ 68.04 kg.
Next, we can calculate the calories burned by multiplying the rate of calories burned per hour by the time spent running.
Calories burned per week = Calories burned per hour × Time spent running in hours
To find the calories burned per week, we need to multiply the calories burned per hour by the number of hours spent running in a week.
Calories burned per week = 740 Cal/h × 3.5 h
= 2590 Cal
Therefore, a person weighing 150 lbs. would burn approximately 2590 calories running for 3 1/2 hours in a week.
