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?
I used MS Excel to develop this linear relationship
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.
