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?

Answer 1

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.

Answer 2

Hi drwls it is not 540 Cal/h it is 740 Cal/h. thanks anyway!

Answer 3

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.
