Question
A train of length 180 m crosses another train of length
120 m coming from the opposite direction. If the speeds of the two trains are 6 m/sec and 9 m/sec respectively, what time will they take to completely pass each other?Solution
ATQ,
Relative speed = 6 + 9 = 15 m/sec
Combined length = 180 + 120 = 300 m
Time taken = 300 / 15 = 20 seconds
