The ratio between the rates of walking of A and B is 2:3 , if the time taken by B to cover a certain distance is 36 minutes, the time taken by A to cover that much distance is ?
-
- 24 min
- 54min
- 48 min
- 21.6min
Correct Option: B
Ratio of speed = 2 : 3
Ratio of times taken for same distance = 1/2 : 1/3
From question 1/2 : 1/3 = t : 36
⇒ (1/3) x t = (1/2) x 36
∴ x = 54 min .
