Question

A train covers a distance of 450 km in 5 hr between station A and station B.
What is average speed of train, (i) in km hr(ii) in ms-.

Answer 1

Explanation:

Let the return speed be x kmhr and the distance be d km Average speed (= frac{{Total;distance}}{{Total;time}}) Average speed (= frac{{d; + ;d}}{{frac{d}{{60}} ...

Answer 2

Explanation:

The distance between the two stations is 240 km. A train takes 4 hours to cover this distance. Calculate the speed of the train.

Speed = (Distance travelled) / (Time)= (240 km) / (4h) = 60 Km/h

Speed = (Distance travelled) / (Time)= (240 km) / (4h) = 60 Km/hTherefore the speed of the train is 60km/hr.
