Question

Raul biked at a steady speed during his 8-mile ride. He finished the ride in 4/5 hour.

Which fraction represents rauls speed in miles per hour

Answer 1

To find Raul's speed in miles per hour, we can use the formula for speed:

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

In this case, the distance is 8 miles, and the time is \( \frac{4}{5} \) hours. We can plug these values into the formula:

\[
\text{Speed} = \frac{8 \, \text{miles}}{\frac{4}{5} \, \text{hours}}
\]

To divide by a fraction, we multiply by its reciprocal:

\[
\text{Speed} = 8 \times \frac{5}{4} = \frac{8 \times 5}{4} = \frac{40}{4} = 10 \, \text{miles per hour}
\]

Thus, Raul's speed is 10 miles per hour. Since you asked for the speed in fraction form, we can express it as:

\[
\frac{10}{1} \text{ miles per hour}
\]

So the fraction representing Raul's speed is \(\frac{10}{1}\).
