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 A 5 mile/minute B 1/5 mile/minute C 1/5 minute/mile D 5 minute/mile

Answer 1

To find the unit rate of how many minutes Liam took to travel one mile, we can divide the total time by the total distance.

Liam took 15 minutes to ride 3 miles.

So, to find the time taken per mile:

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

Thus, the correct unit rate is D) 5 minutes/mile.
