If a man walked W miles in H hours, and then R miles in the same length of time, what is his average rate for the entire trip?

Average speed = Total Distance Traveled / Total Time taken
= (W+R)/2H

If a man walked W miles in H hours, and then R miles in the same length of time, what is his average rate for the entire trip?

Average rate is total distance covered [(W + R) miles] divided by total time taken [(H + H) = 2 H hours] =
