To determine how many miles John runs per hour, we divide the total distance (26.2 miles) by the total time (4 hours).
Total distance = y = 26.2
Total time = x = 4
So, y/x = 26.2/4 = 6.55
Therefore, John runs 6.55 miles per hour.
To determine how many miles John runs per hour, we need to solve the equation 4y = 26.2x, where y represents miles per hour (mph) and x represents time in hours.
First, divide both sides of the equation by 4:
y = (26.2/4)x
Simplifying the equation gives us:
y = 6.55x
This tells us that the number of miles John runs per hour is 6.55 mph.
So, the correct answer is 6.55 mph.
