A train traveling from Mumbai to Goa covered the first 420 km at a speed of 60 km/h and then covered the remaining 195 km at a speed of 65 km/h. Find its average speed in km/h.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. 61.5.
Time for the first part = 420/60 = 7 hours
Time for the second part = 195/65 = 3 hours
Total distance = 420 + 195 = 615 km
Total time = 7 + 3 = 10 hours
Average speed = 615/10 = 61.5 km/h
Therefore, the average speed of the train is 61.5 km/h.
