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 = 30:40 = 3:4 Let the distance covered by A and B be 3x km and 4x km respectively. According to question, => 4x – 3x = 30 => x = 30 Therefore, distance between them before starting = 4x + 3x = 7x = 210 km
