Answer 2

Hey dear,

◆ Answer -

t = 34 s

◆ Explaination-

To pass the flag post, train have to travel a middle distance and its own length.

Total distance travelled -

s = 20 + 320 = 340 m/s

Speed of the train-

v = 36 km/h = 10 m/s

Total time taken to pass flag post,

t = s / v

t = 340 / 10

t = 34 s

Therefore, the train will take 34 s to cross the flag post completely.

Hope this helps you...
