To determine how many miles John runs per hour, we can divide the distance (26.2 miles) by the time (4 hours).
Therefore, the calculation would be: 26.2 miles / 4 hours = 6.55 mph.
So, 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 for y, where x represents the hours and y represents the miles.
Dividing both sides of the equation by 4, we get:
y = 26.2/4x
Simplifying further, we have:
y = 6.55x
From this equation, we can see that the coefficient of x is the ratio of miles to hours. Therefore, the answer is 6.55 mph.
