Question

9. A train travels with a uniform speed of 20kmh and covers a distance of 40 km from station A If the total distance between station A and B is 160km , how fast should the train travel for the remaining distance to reach station B , so that it's average speed for the entire journey is 40kmh.​

Answer 1

Answer:

Answer

Explanation:

We have to find that how fast (means speed) should the train travel while covering the remaining distance, so that its average speed for the entire journey is 40 km/hr. Similarly, time taken by train to cover 40 km at a speed of 20 km/hr. ∴ Remaining Speed = 120/2 = 60 km/hr
