Since, the time taken by A and B is same, therefore the ratio of the distance covered by them will be equal to the ratio of their speeds. Therefore, ratio of the distance covered by A and B = 10:20 = 1:2 Let the distance covered by A and B be x km and 2x km According to the question, 2x – x = 10 Or, x = 10 Therefore, distance between them before starting = x + 2x = 3x = 30 km
