When a train travels at a speed of 90kmph,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 one:
A) 18.75km
B) 50km
C) 60km
D) 85km
E) 95km
Let x be the time reached with the speed 90km/h   50km/h ----&gt; x+15   Distance is equal so   90(km/h)× xhr = 50(km/h) × (x+15) hr   So   90 x = 50x + 750   So the would be in km   18.75kmnd x = 18.75   18.75kmNSWER:18.75km
