a train traveled form its terminal to an ocean resort at 90/km/h and then returned at 72km/h. What is the rail distance between the train terminal and the ocean resort if the round trip travel time was 9 hours?

• 360 km.
  If distance=x, (x/90)+(x/75)=9, On solving, x=360

• Average speed= 2*90*72/(90+72)= 180*72/162= 80 km/hr
  rail distance between the train terminal and the ocean resort = 9*80/2= 360 kms
