Aman and Bhanu, two friends, started running together at
40 m/s and 18 m/s, respectively, along a circular track in the same direction. How long will it take "Aman" to pass "Bhanu" for the first time if the circular track has a radius of 140 meters? (Let π = 22/7)Solution
ATQ, Length of the circular track = 2 × (22/7) × 140 = 880 metres Relative speed of 'Aman' w.r.t that of 'Bhanu' = 40 - 18 = 22 m/s Required time = (880/22) = 40 seconds
