To find out how many miles John runs per hour, we can rearrange the equation given in the problem:
\[ 4y = 26.2x \]
Here, \( y \) represents miles per hour and \( x \) represents hours. We can solve for \( y \) by isolating it:
- Divide both sides by 4:
\[ y = \frac{26.2}{4} x \]
Since John runs for \( x = 1 \) hour, we can plug this value into the equation:
\[ y = \frac{26.2}{4} \]
Now, calculate \( 26.2 \div 4 \):
\[ 26.2 \div 4 = 6.55 \]
Thus, John runs at a speed of:
6.55 mph
So the correct response is:
6.55 mph
