X started to run from point ‘A’ to ‘B’ at a speed of 35 km/hr at 9:00 am and Y started to run from point ‘B’ to ‘A’ at a speed of 11 km/hr at 11:00 am. If they meet each other at 3:00 pm then find the distance between points ‘A’ and ‘B’.
Distance covered by X in 2 hours = 35 × 2 = 70 km Relative speed of X and Y = 35 + 11 = 46 km/hr Sum of distance covered by both in 4 hours = 46 × 4 = 184 km Total distance between points ‘A’ and ‘B’ = 70 + 184 = 254 km
