Question
A and B are travelling towards each other with a speed
of 15 km/hr and 30 km/hr. If they started at same time and A covered 25 km less distance than B before meeting him, then find the distance between them before starting.Solution
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 = 15:30 = 1:2 Let the distance covered by A and B be x km and 2x km According to the question, 2x – x = 25 Or, x = 25 Therefore, distance between them before starting = 2x + x = 3x = 75 km
