Question
Average speed of ‘A’ during a 24-hour journey is 30
km/h. If he covered the first 140 km of his journey at a speed of 10 km/h, then find the speed at which ‘A’ travelled during the remaining journey.Solution
Total distance covered by ‘A’ = 24 × 30 = 720 km Time taken to cover 140 km = 140/10 = 14 hours Time taken to cover remaining distance = 24 – 14 = 10 hours So, required speed = {(720 – 140)/10} = 58 km/h
