the speed of the train is 25m/s multiply with 18/5 to change in km/h 25x18/5 =90km/h
Saismita1:
the given ans is 90km/hr
i said it in m/s
what's the process?
see my answer
i have told the process
distance = length of the train +length of the tunnel so total distance is 210+90=300 so speed = distance by time solve it you will get 25m/s and convert in m/s 25x18/5= 90km/h
i hope you have understood
