Norman traveled 261 miles on a trip to bates. The trip took 4 1/2 hours. If he then drives for 1 1/2 hours to leighsville, which is another 81 miles farther, what its his average rate of travel for the entire trip?

He drives for a total of 6 hours and travels 342 miles.

342 / 6 = ?______ mph

To find the average rate of travel for the entire trip, you need to divide the total distance traveled by the total time taken.

First, let's find the total distance traveled by Norman. He traveled 261 miles on the trip to Bates and an additional 81 miles to Leighsville. So, the total distance traveled is 261 + 81 = 342 miles.

Next, let's find the total time taken by Norman. On the trip to Bates, he took 4 1/2 hours (which is equivalent to 4.5 hours), and then he drove for another 1 1/2 hours (which is equivalent to 1.5 hours) to Leighsville. So, the total time taken is 4.5 + 1.5 = 6 hours.

To find the average rate of travel, divide the total distance traveled (342 miles) by the total time taken (6 hours):

Average Rate of Travel = Total Distance ÷ Total Time
Average Rate of Travel = 342 miles ÷ 6 hours

Calculating this, we find that the average rate of travel for the entire trip is:

Average Rate of Travel = 57 miles per hour
