When a train travels at a speed of 100kmph,it reaches the destination on time.when the same train travels at a speed of 50kmph,it reaches its destination 15min late.what is the length of journey?
Choose the correct choice from the following options:  A) 15km  B) 50km  C) 60km  D) 85km  E) 95km
Let x be the time reached with the speed 100km/h   50km/h ----&gt; x+15   Distance is equal so   100(km/h)× xhr = 50(km/h) × (x+15) hr   So   100 x = 50x + 750   So the would be in km   15kmnd x = 15   15kmNSWER:15km
