To determine how many miles John runs per hour, we need to find the value of x when y = 1.
From the given proportional relationship 4y = 26.2x, we can substitute y = 1:
4(1) = 26.2x
4 = 26.2x
x = 4/26.2
x ≈ 0.152
Therefore, John runs approximately 0.152 miles per hour.

To determine how many miles John runs per hour, we need to find the value of x when y = 1.
From the given proportional relationship 4y = 26.2x, we can divide both sides by 4 to isolate x:
y = 26.2x/4
y = 6.55x
So, John runs approximately 6.55 miles per hour.
