To determine how many miles John runs per hour, we need to solve the equation 4y = 26.2x for y (miles per hour).
Dividing both sides of the equation by 4, we get:
y = 6.55x
Therefore, John runs at a speed of 6.55 miles per hour.
So the correct answer is 6.55 mph.
To determine how many miles John runs per hour, we need to solve the given proportional relationship equation, 4y=26.2x, where x represents the number of hours and y represents the number of miles.
Dividing both sides of the equation by 4 to isolate y, we have:
y = (26.2/4)x
y = 6.55x
So, the number of miles John runs per hour is 6.55 miles per hour. Therefore, the correct answer is 6.55 mph.
