3.A train travels 50% faster than a car. Both started from Bombay at the same time and also reached Pune at the same time. However, the train lost 12.5 min while stopping at a station. Find the speed of the train if the distance between Bombay and Pune is 75km.

• 180 kmph
  
  If speed(kmph) of a car=x ,then speed of the train=1.5x, total distance traveled=75 km.
  Here Time(in hr.) taken by train+stoppage =Time taken by car
  (75/1.5x)+(12.5/60)=75/x, On solving x=120
  So speed of the train=1.5*120=180

• Speed of car=120km/h
  speed of train=180km/h
  
  (3v/2)×t=75 km
  Then vt=50 km..........(1)
  
  v×(t+12.5/60)=75 km ..........(2)
  
  from (1)and (2)
  v=120 km/h
  where v = speed of car
