To find how many miles 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:
(4/26.2)y = x.
Simplifying the fraction:
0.153 y = x.
Therefore, John runs at a speed of about 0.15 miles per hour. Answer: 0.15 mph.
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)
