Buses A and B are moving around a circular ground of radius 280 m. If the speeds of the buses A and B are 12 m/sec and 20 m/sec respectively, then what is the difference between the time taken by bus A and B to complete 3 round of the ground?
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 = (1760/12) × 3 = 440 Time taken by bus B to cover 3 rounds of a ground = (1760/20) × 3 = 264 Required difference = 440 – 264 = 176
