343.75 miles per hour
55 miles per hour
137 miles per 2 hours
5.5 miles per hour

Answer 1

To find the unit rate of 137.5 miles in 2.5 hours, you divide the total miles by the total hours:

\[
\text{Unit rate} = \frac{137.5 \text{ miles}}{2.5 \text{ hours}}.
\]

Calculating that:

\[
\frac{137.5}{2.5} = 55 \text{ miles per hour}.
\]

So the answer is **55 miles per hour**.
