Answer 2

Answer:

B. 107.25

Step-by-step explanation:

Let x be the calories burnt by the man,

Since, when a person runs 1 miles in 8 minutes,

Then,

$\frac{\text{Calories used by him}}{\text{His weight in lb}}=65\%$,

Given,

Weight of the person = 165 lb,

Thus,

$\frac{x}{165}=\frac{65}{100}$,

$x = \frac{165\times 65}{100}$

$x=\frac{10725}{100}$

$\implies x=107.25$

Hence, 107.25 calories will be used.
