Question

the train traveled at an average speed of 48 miles per hour for the first 2 hours and at 60 miles an hour for the next hours. What was the train's average speed for the 6-hour trip? ( Average speed equals total miles divided by total time.)

Answer 1

Answer: 56 mph

Explanation:

48 miles x 2 hours = 96 miles

60 miles x 4 hours = 240 miles

240 + 96 = 360 total miles

360 / 6 (hours) = 56 mph
