Question

A train travels at a speed of 60 km per hour for 0.52 hrs ,at 30 km per hour the next 0.24 hr and then at 70 km per hour for the next 0.71 hour .what it the average speed

Answer 1

Average speed = total distance / total time
Since distance = speed x time
60x0.52=31.2
30x0.24=7.2
70x0.71=49.7
Average speed =31.2+ 7.2+ 49.7/0.52+ 0.24 +0.71
=88.1/1.47
=59.9
