Answer:

Ravi’s average speed is 7 miles per hour

Step-by-step explanation:

In this question, we are tasked with calculating what Ravi’s average speed was.

We must know that the term average speed is mathematically equal to Total distance/ Total time

We already have the time of 3 hours, what is needed is the distance.

From the question, we can see that they met at the point where Pilar had travelled 55 miles. What this means is that Ravi would have traveled (55-34) miles to this point since they are coming in opposite direction. This means that Ravi had traveled 21 miles

Thus his average speed is 21 miles/ 3 hours = 7 miles per hour
