Answer 1

If you would like to know the average speed for the round trip, you can calculate this using the following steps:

5 hours + 6.5 hours = 11.5 hours
240 miles * 2 = 480 miles

11.5 hours ... 480 miles
1 hour ... x miles = ?

11.5 * x = 480 * 1
11.5 * x = 480 /11.5
x = 480 / 11.5
x = 41.74 miles per hour

The correct result would be 41.74 miles per hour.
