It took Liam 15 minutes to ride his bike three miles. Convert this ratio into a unit rate by finding how long many minutes did he take to travel one mile.(1 point) Responses 15 minutes/mile one-fifth minutes/mile 5 minutes/mile 5 minutes/mile 15 miles/minute one-fifth miles/minute 5 miles/minute

To find out how many minutes it took Liam to travel one mile, we can set up the unit rate based on the information given.

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

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

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