A train can travel 50% faster than a car. Both start from point A at the same time and reach point B 75 kms away from A at the same time. On the way, however, the train lost about 12.5 minutes while stopping at the stations. The speed of the car is:

A. 100 kmph B. 110 kmph
C. 120 kmph D. 130 kmph

• If c is speed of car and T is speed of train, T = n1.5c, then
  
  75/c - 75/1.5c = 12.5/60
  
  solving this eqn, we get
  
  c= 120 kmph .. option D

• Let speed of the car be x kmph.
  
  Then, speed of the train = 150 /100x = 3/2 x kmph.
  
  (75 /x)- 75 /(3/2)x= 125 /10*60
  
  (75 /x)- (50/x) = 5 /24
  
  x=25*24/5=120kmph
  
  x = 25 x24 = 120 kmph.
