Pilar and Ravi start at opposite ends o a a 55-mile bike trail. They start riding their bikes toward each other at the same time. After 3 hours, they meet. Pilar rides 34 miles before they meet. What is Ravi's average speed?

7 mph

Step-by-step explanation:

Since Pilar rode 34 miles before they met, then we can find the distance Ravi rode before they met.

They started 55 miles away from one another. Therefore, the distance Ravi rode was:

55 - 34 = 21 miles

It took both of them 3 hours to meet.

Average speed is given as total distance divided by total time taken. Mathematically:

S = D / t

Therefore, Ravi's average speed is:

S = 21 / 3 = 7 mph

His average speed was 7 mph.
