Question
Buses A and B are moving around a circular ground of
radius 280 m. If the speeds of the buses A and B are 15 m/sec and 24 m/sec respectively, then what is the difference between the time taken by bus A and B to complete 3 round of the ground?Solution
Circumference if the ground = 2πr = 2 × 22/7 × 280 = 1760 m So, distance = 1760 m Time taken by bus A to cover 3 rounds of a ground = (1760/15) × 3 = 352 Time taken by bus B to cover 3 rounds of a ground = (1760/24) × 3 = 220 Required difference = 352 – 220 = 132
