Final answer:
Paul's average rate per hour was 8 miles per hour, found by dividing the distance he ran (22 miles) by the time it took (2.75 hours).
Step-by-step explanation:
Paul ran 22 miles in 2.75 hours. To find his average rate per hour, you would divide the total distance by the total time. By performing this division, you calculate Paul's average speed.
The formula to find the average speed is:
\[\text{Average speed} = \frac{\text{Distance}}{\text{Time}}\]
Substituting the given values into the formula, we get:
\[\text{Average speed} = \frac{22 \text{ miles}}{2.75 \text{ hours}}\]
By calculating this, we find:
\[\text{Average speed} = 8 \text{ miles per hour}\]
Therefore, Paul's average rate per hour was 8 miles per hour.
