Question
Determine the time difference for two buses, one with a
length of 200 meters and the other with a length of 150 meters, as they travel at speeds of 54 kmph and 72 kmph, respectively, to pass each other in the same direction and opposite direction.ÂSolution
ATQ, Total length to be travelled by the bus in order to cross each other = 200 + 150 = 350 m While travelling in same direction, Relative speed of the bus = 72 – 54 = 18 km/hr = 18 × (5/18) = 5 m/sec Required time taken = (350/5) = 70 sec While travelling in opposite direction, Relative speed of two buses = 72 + 54 = 126 km/hr = 126 × (5/18) = 35 m/sec Required time taken = (350/35) = 10 sec Required difference = 70 – 10 = 60 sec
