Question
Buses A and B are moving around a circular ground of
radius 210 m. If the speeds of the buses A and B are 16 m/sec and 20 m/sec respectively, then what is the difference between the time taken by bus A and B to complete 2 round of the ground?Solution
Circumference if the ground = 2Ï€r = 2 x 22/7 x 210 = 1320 m So, distance = 1320 m Time taken by bus A to cover 2 rounds of a ground = (1320/16) x 2 = 165 Time taken by bus B to cover 3 rounds of a ground = (1320/20) x 2 = 132 Required difference = 165 - 132 = 33
