Question
Average speed of ‘A’ during a 24-hour journey is 38
km/h. If he covered the first 120 km of his journey at a speed of 20 km/h, then find the speed at which ‘A’ travelled during the remaining journey.Solution
Total distance covered by ‘A’ = 24 × 38 = 912 km Time taken to cover 120 km = 120/20 = 6 hours Time taken to cover remaining distance = 24 – 6 = 18 hours So, required speed = {(912 – 120)/18} = 44 km/h
