Answer 1

the answer is 107.25

Explanation:

Answer 2

B. 107.25

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,

`(x)/(165)=(65)/(100)`,

`x = (165* 65)/(100)`

`x=(10725)/(100)`

`\implies x=107.25`

Hence, 107.25 calories will be used.
