Speed of a car is (v + 5) km/h, which is 7 km/h less than that of bike. Time taken by car to cover 72 km is 25% less than the time taken by bike to cover 120 km. Length of a train is (5v + 11) metres. If speed of train is (v - 2) m/s, then find the time taken (in seconds) by train to cross a man standing on a platform of length 360 metres.
