Question

5. A man walks at the speed of 4 km/h. A train coming from behind him at 22 km/h passes by him in 30 s. Find the length of the train.
​

Answer 1

Answer:

the train length is 143m or 14300 cm

Answer 2

relative velocity of the train is 18 km/h

convert this to m/s

you get 18000/3600 which is 5m/s

at 5m/s the train passes in 30s

so length of train is 5m/s multiplied by 30s which is 150m
