Question
During a 1.2 km race, runner 'P' gives runner 'Q' a start
of 200 metres but still wins by 100 metres. If 'Q' completes the race in 12 minutes, determine the time taken by 'P'.Solution
ATQ,
Distance covered by 'Q' when 'P' finishes 1200 m = 1200 - 200 - 100 = 900 m
Speed ratio (P : Q) = 1200 : 900 = 4 : 3
Time ratio = 3 : 4
Time taken by P = (12/4) Γ 3 = 9 minutes
