Question
A cat, running at a speed of 54 km/h and positioned 240
meters ahead of a dog, can be caught by the dog in 6(2/3) seconds. Determine the time it takes for the dog to overtake a bus traveling at 21 m/s. The bus can pass a stationary man in 21(2/3) seconds, and there is no initial separation between the bus and the dog. (Note: The lengths of the cat and the dog are considered negligible.)Solution
ATQ, Speed of the Cat = 54 Ă— (5/18) = 15 m/s Distance covered by the dog in 6(2/3) seconds = 240 + distance covered by the cat in 6(2/3) seconds = 240 + 15 Ă— (20/3) = 240 + 100 = 340 metres So, speed of the dog = 340 Ă· (20/3) = 51 m/s Relative speed of the dog with respect to the bus = 51 – 21 = 30 m/s Length of the bus = 21(2/3) Ă— 21 = (65/3) Ă— 21 = 455 metres So, time taken by the dog to overtake the bus = 455/30 = 91/6 secondsÂ
