Question
A and B are travelling towards each other with a speed
of 10 km/hr and 20 km/hr. They started at same time and A covered 20 km less distance than B before meeting B. Find the distance between them before starting.Solution
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 = 10:20 = 1:2 Let the distance covered by A and B be x km and 2x km respectively. According to question, => 2x – x = 20 => x = 20 Therefore, distance between them before starting = 2x + x = 3x = 60 km
