Q. A train can travel 50% faster then a car.Both started at point A at the same time and reached point B 75 km away from A at the same time. On the way, however the train lost about 12.5 minutes while stoping at the stations. Find the speed of car :

• Let speed of car be x kmph.
  Then the speed of train = (150/100)*x
  = (3/2)*x
  
  Therefore,
  (75/x) - (75/(3/2)*x) = 12.5/60
  (75/x) - (50/x) = 5/4
  x = (25*24)/5
  x = 120 kmph
  The speed of car is 120 kmph.

• train's speed-s,car's speed-s/2
  (75/s)+(12.5/60)=75/(s*2)
  =>s=360
  car's speed=180 kmph
