Average speed of ‘A’ during a 24-hour journey is 32 km/h. If he covered the first 160 km of his journey at a speed of 20 km/h, then find the speed at which ‘A’ travelled during the remaining journey.
Total distance covered by ‘A’ = 24 × 32 = 768 km Time taken to cover 160 km = 160/20 = 8 hours Time taken to cover remaining distance = 24 – 8 = 16 hours So, required speed = {(768 – 160)/16} = 38 km/h
