To determine how many miles John runs per hour, we need to find the value of x when y = 1.
Given the proportional relationship equation: 4y = 26.2x
Let's substitute y = 1 into the equation:
4(1) = 26.2x
4 = 26.2x
To find x, divide both sides of the equation by 26.2:
x = 4 / 26.2
x ≈ 0.152
Therefore, John runs approximately 0.152 miles per hour.
The correct response is: 0.15 mph
