John runs a marathon (26.2 miles) in 4 hours. Determine how many miles he runs per hour if the proportional relationship is represented by 4y=26.2x .(1 point)
To determine how many miles John runs per hour, we need to find the value of x when y = 1 (1 hour).
From the proportional relationship 4y = 26.2x, we substitute y = 1:
4(1) = 26.2x
4 = 26.2x
x = 4 / 26.2
x ≈ 0.153
Therefore, John runs approximately 0.153 miles per hour.
