Question

On a brisk walk, a person burns about 340 Cal/h. At this rate, how many hours of brisk walking would it take to lose 1 lb of body fat? (A pound of body fat stores an amount of chemical energy equivalent to 3,500 Cal.) answer:____h

Answer 1

Given:

Amount of fat stored in Cal = 3500 Cal

Rate at which the person burns = 340 Cal/h

Let's find the number of hours it would take the person to lose 1 lb of fat.

Given that the person burns at a rate of 340 Cal/h, the time it will take the person to lose 1 lb will be:

$\begin{gathered} t=\frac{3500\text{ Cal}}{340\text{ Cal/h}} \\ \\ t=10.29\text{ hours} \end{gathered}$

Therefore, the time it will take the person to burn 1 lb of fat is 10.29 hours.

ANSWER:

10.29 h
