Question

Kenneth ran a marathon (26.2 miles) in 5.5 hours. What was Kenneth’s average speed? (Round your answer to the nearest tenth.)

0.2 mph
4.8 mph
5.5 mph
144.1 mph

Answer 1

To find Kenneth's average speed, we can use the formula:

\[
\text{Average Speed} = \frac{\text{Total Distance}}{\text{Total Time}}
\]

In Kenneth's case, the total distance is 26.2 miles and the total time is 5.5 hours.

Now we can calculate the average speed:

\[
\text{Average Speed} = \frac{26.2 \text{ miles}}{5.5 \text{ hours}} \approx 4.763636364 \text{ mph}
\]

Rounding to the nearest tenth:

\[
\text{Average Speed} \approx 4.8 \text{ mph}
\]

So, Kenneth’s average speed was **4.8 mph**.
