Question
Buses A and B are moving around a circular ground of
radius 140 m. If the speeds of the buses A and B are 11 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?Solution
Circumference if the ground = 2πr = 2 × 22/7 × 140 = 880 m So, distance = 880 m Time taken by bus A to cover 3 rounds of a ground = (880/11) × 3 = 240 Time taken by bus B to cover 3 rounds of a ground = (880/20) × 3 = 132 Required difference = 240 – 132 = 108
