Question
Two trains, one 100 m and the other 80 m in length, are
running in opposite directions at speeds of 8 m/sec and 7 m/sec. How long will they take to pass one another?Solution
ATQ,
Two trains move in opposite directions, so their speeds add up: 8 + 7 = 15 m/s Combined length to pass each other: 100 + 80 = 180 meters Time = Distance ÷ Speed 180 ÷ 15 = 12 seconds
