Time taken to cover the first distance: Distance = 240 km, Speed = 60 km/h Time = Distance / Speed = 240 / 60 = 4 hours. Time taken to cover the second distance: Distance = 180 km, Speed = 90 km/h Time = Distance / Speed = 180 / 90 = 2 hours. Total distance = 240 + 180 = 420 km. Total time = 4 + 2 = 6 hours. Average speed = Total distance / Total time = 420 / 6 = 70 km/h. Correct option: a) 70 km/h
