in the first case, the total distance travelled by the train is 160 + 120 = 280

time taken is 14sec therefore speed = distance / time = 280 / 14 = 20m/s

Now in the second case, the distance travelled by the train is 100 plus 120 = 220m and speed of the train is 20m/s

therefore time = distance/ speed = 220 / 20 = 11seconds.

Please approve if you like and understand my solution and feel free to ask any other doubt :)
