Car A with wheel of diameter 35 cm makes 40000 rotations per hour and car B with diameter 42 cm makes 50000 rotations per hour. Car A is chased by B from an initial separation of ‘x’ meters and overtakes it in 79.2 seconds. How much time would have been taken to overtake if car A has wheels rotating at a rate of 45000 rotations per hour (in seconds)?
