John runs a marathon (26.2 miles) in 4 hours. Determine how many mile he runs per hour if the proportional relationship is represented by 4y = 26.2x
To find the number of miles John runs per hour, we can solve the equation for x by dividing both sides of the equation by 26.2:
4y = 26.2x
x = (4y) / 26.2
Since y represents the number of hours and x represents the number of miles, x / y represents the miles per hour. So, the number of miles John runs per hour is:
x / y = ((4y) / 26.2) / y
= 4 / 26.2
≈ 0.152
Therefore, John runs approximately 0.152 miles per hour.
