Question 756297: to burn 1 pound a person needs to burn 3,500 calories
bicycling 6 mi/hour burns 240 calories/ hour for a 150 pound person.
Assuming that the calories burned are proportional, at what rate would a 120 pound person burn calories while bicycling at 12 mi/hour?

Hello,
Since bicycling 6 mi/hour burns 240 calories/ hour, bicycling at 12 mi/hour would burn 240*12/6=480 calories/hour for a 150 pound person, so bicycling at that speed would burn 480*4/5=392 calories/hour for a 120 pound person.
