When a train travels at a speed of 80kmph,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:
A) 25km
B) 50km
C) 60km
D) 85km
E) 95km
Let x be the time reached with the speed 80km/h   50km/h ----&gt; x+15   Distance is equal so   80(km/h)× xhr = 50(km/h) × (x+15) hr   So   80 x = 50x + 750   So the would be in km   25kmnd x = 25   25kmNSWER:25km
