D. 266.13

Answer :

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,

[tex]\frac{\text{Calories used by him}}{\text{His weight in lb}}=65\%[/tex],

Given,

Weight of the person = 165 lb,

Thus,

[tex]\frac{x}{165}=\frac{65}{100}[/tex],

[tex]x = \frac{165\times 65}{100}[/tex]

[tex]x=\frac{10725}{100}[/tex]

[tex]\implies x=107.25[/tex]

Hence, 107.25 calories will be used.
