Question

Janice walks a total of 7/8
hour. She walks at a rate of 1 mile every 1/4
hour. How many miles did she walk?

Answer 1

To find out how many miles Janice walked, we can use the formula for distance:

\[
\text{Distance} = \text{Rate} \times \text{Time}
\]

First, we need to determine the total time Janice walked in hours and her walking rate in miles per hour.

1. **Time:** Janice walked for \( \frac{7}{8} \) hour.
2. **Rate:** Janice walks 1 mile every \( \frac{1}{4} \) hour. To convert this to miles per hour:

\[
\text{Rate} = \frac{1 \text{ mile}}{\frac{1}{4} \text{ hour}} = 1 \text{ mile} \times \frac{4}{1} = 4 \text{ miles per hour}
\]

Now we can compute the distance she walked:

\[
\text{Distance} = \text{Rate} \times \text{Time} = 4 \text{ miles per hour} \times \frac{7}{8} \text{ hour}
\]

Calculating the distance:

\[
\text{Distance} = 4 \times \frac{7}{8} = \frac{28}{8} = \frac{7}{2} = 3.5 \text{ miles}
\]

Thus, Janice walked **3.5 miles**.
