Here time taken by both A and B is same, so 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 = 20:30 = 2:3 Let the distance covered by A and B be 2x km and 3x km respectively. According to question, => 3x – 2x = 30 => x = 30 Therefore, distance between them before starting = 3x + 2x = 5x = 150 km
