If Peter expends 1,500 calories running a mile in one hour and Samantha burns 1,500 calories riding a bike in forty-five minutes. Which one of the two the greatest amount of energy? Group of answer choices A) SamanthaB) PeterC) They are the same

Respuesta :

Answer:

Both consume the same amount of energy ( 1500 cal) → Option C

But if both would exercise the same amount of time, then Samantha would consume 1.33 times the amount of Peter → Option A

Explanation:

Taking into account the total amount of enery consumed, for both Peter and Samantha is the same. Energy consumed= 1500 calories

Regarding the rate of energy consumption ( energy consumption per unit of time) , then peter expends 45 minutes , then

Rate of energy consumption of Peter = 1500 cal/ 60 min =25 cal/min

for Samantha

Rate of energy consumption of Samantha =  1500 cal/ 45 min =33.33 cal/min

Both spend the same time during exercises , then Samantha spends:

33.33 cal/min/25 cal/min = 1.33 times the amount spend by Peter
