Quizplus · Accepted Answer

The average velocity is the total distance divided by the total time. The time for the first 100 miles is 100/60 hours, and for the next 50 miles is 50/55 hours. The total time is (100/60) + (50/55) hours. The average velocity is 150 miles divided by this total time, which is approximately 58.2 mi/h.
