Problem Statement
Two trains of lengths 200 m and 150 m run in opposite directions at 90 km/h and 54 km/h. In how many seconds do they completely cross each other?
Explanation
Relative speed is the sum. Ninety plus fifty four equals one hundred forty four km per hour which is forty meters per second. Total length is three hundred fifty meters. Time is three hundred fifty over forty equals eight point seven five seconds.
