$2.604$ miles per hour

Explanation:

I used MS Excel to develop this linear relationship

$y = 0.0333 x - 0.0867$

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.

$0.0333 x = 0.0867$

$x = \frac{0.0867}{0.0333} = 2.604$ mph
