Question

Kevin sweats .08 L/min when jogging at 5mph, and .18 L/min when running at 8mph. consider a linear relationship, at what speed will Kevin stop sweating?

Answer 1

`2.604` miles per hour

Explanation:

I used MS Excel to develop this linear relationship

`y=0.0333x -0.0867`

When y (which is sweating rate as liters per min) is zero, your x (jogging rate of Kevin) is 2.604 mph. It means that when jogging rate is 2.604 mph, Kevin does not sweat.

`0.0333x = 0.0867`

`x= 0.0867/0.0333 = 2.604` mph
