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 .
To determine how many miles John runs per hour, we need to solve the equation 4y = 26.2x for y, where y represents the number of miles John runs per hour and x represents the time in hours.
To solve for y, divide both sides of the equation by 4:
y = 26.2x/4.
This equation tells us that the number of miles John runs per hour is equal to 26.2/4 = 6.55 miles.
Therefore, John runs approximately 6.55 miles per hour.
