Answer:

Speed of man = 3 km/hr

Speed in m/sec = (3 x 5/18 F 5/6 m/s

Distance covered by man in 4 min = (5 x 4

x 60)/6 = 200 m

Total distance travelled by the train 100

+200 300 m

Time taken by the train to travel 300 m =

4 min

Speed of the train = 300/240 = 5/4 m/sec

Speed in Km/hr = (5/4 x 18/5) = 4.5 km/h.
