an express train was running at an average speed of 100kmph stopping for 3mins after every 75kms.the time taken by the train to reach the destination at a distance of 600km is?

• 600/75 = 8 parts if 600 km is divided in 75 km i.e train has to stop 8 times
  but at last no need to stop at a gap of 75 because train finally reaches the destination
  so train only stops 7 times time spend is 7*3 = 21 minute
  100 km /hr so time to travel 600 km is 6 hr + 21 minute extra
  total time is 6hr+21min

• 75+150+......600
  600=75+(n-1)*75
  n=8
  so train will stop at 8 places
  but 8th place is destination
  so number of stoppage in path=7
  time spend in stoppage =3*7=21min
  time to reach the destination=600/100=6hr
  total time=6hr21min

• when the total journey of 600 kms is divided into intervals of 75 km 8 such intrvls are obtained... so the train stops 7 times=7*3=21 mins
  time taken by the train to cover 75 km at 100 kmph=36mins
  so total time for travel=36*8=288
  time required to reach destination=288+21=309mins
