Question
Average speed of ‘A’ during a 20-hour journey is 30
km/h. If he covered the first 240 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’ = 20 × 30 = 600 km Time taken to cover 240 km = 240/20 = 12 hours Time taken to cover remaining distance = 20 – 12 = 8 hours So, required speed = {(600 – 240)/8} = 45 km/h
