Question

A trean leave new delhi at 1915hour areave mathura at 2205 hours the distance between two station is 144km .find the speed?

Answer 1

Total time taken to reach Mathura is 2hrs 50min
so,speed=Distance/Time
=144÷2.50
=57.6km/hr

Answer 2

speed = distance/time
divide the distance between the cities by the time taken to reach Mathura from Delhi

1915 - 2205 = 2hrs 50min
= 2.83hrs(approx.)
therefore –
= 144km (distance)/2.83hrs (time)
= 50.8km/hr
