Two trains of lengths 100 m and 150 m are travelling in
opposite directions at speeds of 75 kmph and 50 kmph respectively. What is the time taken by them to cross each other?Solution
Relative speed = 75 + 50 = 125 kmph `=125xx5/18` m/s Total distance = 150 + 100 = 250 m Time taken to cross each other `= (250xx18)/(125xx5) = 7.2`
