To find the rate at which the car is traveling, you can use the formula for speed:

\[
\text{Speed} = \frac{\text{Distance}}{\text{Time}}
\]

In this case, the distance is 157.5 miles and the time is 2.5 hours. Plugging in these values:

\[
\text{Speed} = \frac{157.5 \text{ miles}}{2.5 \text{ hours}} = 63 \text{ miles per hour}
\]

Thus, the car is traveling at a rate of **63 miles per hour**.
