A marathon runner is training for his next race. On his daily run he completes 21.6 mile and burns 2,274 calories. What is his rate of calories burned per mile?
To find the rate of calories burned per mile, divide the total number of calories burned by the total number of miles run.
Rate of calories burned per mile = Total calories burned / Total miles run
Rate of calories burned per mile = 2274 calories / 21.6 miles
Rate of calories burned per mile ≈ 105.28 calories/mile
Therefore, the marathon runner burns approximately 105.28 calories per mile.
