Question
A bus of length 150 meters can cross a signal post in 6
seconds. A second bus traveling at three times the speed of the first bus can cross a car traveling in the opposite direction in 8 seconds. Find the length of the car.Solution
ATQ, Speed of the first bus = 150/6 = 25 m/s Speed of the second bus = 3×25 = 75 m/s Relative speed = 25+75 = 100 m/s Total distance covered by the second bus in 8 seconds = 100×8 = 800 meters Length of the car = 800−150 = 650 meters So, the length of the car is 650 meters.
