Question
A was travelling from point X to point Y. He increased
his speed by 12 km/h after every hour. He reached his destination in 16 hours. If his initial speed was 50 km/h, then what was his average speed in the whole journey?Solution
Total distance travelled by A = (16/2) × {2 × 50 + (16 – 1) × 12} = 12 × (100 + 180) = 2240 km Required average speed = 2240/16 = 140 km/h
