Correct option is A
Given:
Length of two trains = 240m and 320m
Speed of train = 59km/hr and 50 km/hr respectively
Formula Used:
Time =
Solution:
Relative speeds of train when moving in same direction = 59 - 50 = 9km/hr
Speed in metre per second = = 2.5m/sec
Total distance = Total length of train = 240 + 320 = 560metres
Time taken to cross = = 224seconds
Time in minutes = = 3 minutes 44 seconds
