To find the speed at which John runs per hour, we need to solve for x in the equation 4y = 26.2x.
Divide both sides of the equation by 26.2:
x = (4y) / 26.2
Now, substitute the value of y with 1 (since we want to find the speed per hour):
x = (4 * 1) / 26.2
x = 4 / 26.2
x ≈ 0.1527
Therefore, John runs approximately 0.15 miles per hour. So the correct answer is 0.15 mph.
