Answer 1

To find the unit rate for how long it took Liam to travel one mile, we can set up the calculation as follows:

Liam took 15 minutes to ride 3 miles. To determine the time per mile, we can divide the total time by the number of miles:

\[
\text{Time per mile} = \frac{15 \text{ minutes}}{3 \text{ miles}} = 5 \text{ minutes/mile}
\]

Therefore, the answer is **5 minutes/mile**.
