Correct option is
Ratio of the speeds of A and B = 2 : 3. Let the speed of A=2x km/min Hence the speed of B=3x km/min B takes 24 minutes to cover some distance. Hence, Distance=Time×Speed=24×3x=72x For A, Time=SpeedDistance=2x72x=36 Hence, the time taken by A to cover the same distance is 36 minutes.
