Answer 1

if a 160 pound person burns 73 calories in 20 minutes. show linear model on how long it takes to burn 438 calories?

 let x = the rate the calories are burned

in this problem the weight of the person is not needed.

rate * time = total calories burned

x * 20 = 73

20x = 73

x = 73/20 = 3.65 calories burned per minute is the rate

apply this rate to 438 calories to find the time needed to burn them.

438/ 3.65 = 120 minutes
