When a train travels at a speed of 110kmph,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?	Options
A) 12.5km
B) 50km
C) 60km
D) 8.5km
E) 9.5km
Let x be the time reached with the speed 110km/h   50km/h ----&gt; x+15   Distance is equal so   110(km/h)× xhr = 50(km/h) × (x+15) hr   So   110 x = 50x + 750   So the would be in km   12.5kmnd x = 12.5   12.5kmNSWER:12.5km
