Question

a train leaves new Delhi at 1915 hours and arrives mathura at 2205 distance between two stations in 144 km .find the speed of the train.

Answer 1

speed= distance/time

time taken for the journey = 2hrs 50 minutes
=> (2×3600)+(50×60) = 7200+3000 = 10200 seconds

distance covered = 144000 meters


speed = 144000/10200
=> 1440/102 = 14.12 m/s

Answer 2

train leaved ar 19hr 15 min and arrived at 22he 05 min

time taken.=2hr50min
=2+50/60
=12+5 /7
=17/7 Hr


Now total distance travelled=144Km.

So Speed =144÷17/7
=144×7/17
=59.294... Km/Hr (approx)
