Given,
Distance between two cities A and B = 620 Km
Total time taken by a train traveling between A and B = 5 hours and 15 minutes
Total time spent by the train to halt at intermediate stations = 25 minutes
To find,
The approximate average speed of the train between A and B excluding the time it was stopped at other stations.
Solution,
We can simply solve this numerical problem by using the following process:
Mathematically,
speed (s) = distance traveled (d)/time taken(t)
Now,
Total time taken by the train in traveling between A and B, excluding the halting time
= Total time taken by a train traveling between A and B - Total time spent by the train to halt at intermediate stations
= (5 hours and 15 minutes) - (25 minutes)
= 4 hours 50 minutes
= 4(5/6) hours
= 29/6 hours
Now,
The approximate average speed of the train between A and B excluding the time it was stopped at other stations
= total distance traveled / total time taken by the train in traveling between A and B, excluding the halting time
= (620Km) / (29/6 hours)
= 128.28 Km/hr
= 130 Km/hr (approximately)
Hence, the approximate average speed of the train between A and B excluding the time it was stopped at other stations is equal to 130 Km/hr.
