To find the unit rate in miles per hour, you can divide the total miles traveled by the total hours spent traveling.
The train travels 813.5 miles in 55 hours.
We calculate the unit rate as follows:
\[
\text{Unit rate} = \frac{\text{Total miles}}{\text{Total hours}} = \frac{813.5 \text{ miles}}{55 \text{ hours}}
\]
Now, let's perform the calculation:
\[
\frac{813.5}{55} \approx 14.78
\]
Calculating the division gives:
\[
\text{Unit rate} \approx 14.78 \text{ miles/hr}
\]
