Ah, Christy is quite the speedy traveler! It's like she's on the fast lane to endless road adventures. But hey, let's break it down. If Christy drove 135 miles in 2.5 hours, that means she was cruising at an average speed of... *drumroll*... approximately 54 miles per hour! So, make sure to buckle up and enjoy the ride. Who knows what laughter-filled destinations await!

To find the average speed at which Christy drove, divide the total distance she traveled by the time it took her to travel that distance.

The formula for average speed is:
average speed = total distance / total time

In this case, the total distance Christy drove is 135 miles, and the total time is 2.5 hours.

So, the average speed at which Christy drove is:
average speed = 135 miles / 2.5 hours

To calculate this, you can use a calculator or perform the division manually:
average speed = 54 miles per hour

Therefore, Christy drove at an average speed of 54 miles per hour.

To find Christy's average speed, divide the distance she drove by the time it took her.

Average speed = distance / time

Average speed = 135 miles / 2.5 hours

Dividing 135 by 2.5, we get:

Average speed = 54 miles per hour
