Question
X started to run from point ‘A’ to ‘B’ at a
speed of 30 km/hr at 9:00 am and Y started to run from point ‘B’ to ‘A’ at a speed of 14 km/hr at 11:00 am. If they meet each other at 3:00 pm then find the distance between points ‘A’ and ‘B’.Solution
Distance covered by X in 2 hours = 30 × 2 = 60 km Relative speed of X and Y = 30 + 14 = 44 km/hr Sum of distance covered by both in 4 hours = 44 × 4 = 176 km Total distance between points ‘A’ and ‘B’ = 60 + 176 = 236 km
