Question

Jerome burned 75 calories in 15 minutes on a stationary bicycle how many calories will he burn in 25 minutes

Answer 1

For this one, you have to find the rate that he's burning calories. 75 calories in 15 minutes. So you divide 75/15 to get the per minute ratio. 75/15=5 so he burns 5 calories every minute. If he kept that up for 25 minutes, he would burn 5*25=125 calories
