When a train travels at a speed of 70kmph,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 answers: A) 37.5km B) 50.5km C) 60km D) 85.5km E) 95km
Let x be the time reached with the speed 70km/h   50km/h ----&gt; x+15   Distance is equal so   70(km/h)× xhr = 50(km/h) × (x+15) hr   So   70 x = 50x + 750   So the would be in km   37.5kmnd x = 37.5   37.5kmNSWER:37.5km
