Question
A train takes to cross a man standing on a platform and
a 360m long bridge 12 sec and 30 sec respectively. How long will it take to cross a 220m long platform?Solution
Ixambee Method: Time taken to cover only bridge = 30 - 12 = 18 hence Speed of the train = 360/18 = 20m/s So time taken to cover 220 m platfrom only = 220/20 = 11 s So total time to cross 220 m platform = 11 + 12 = 23s
