    speed of 25 km/hr at 9:00 am and Y started to run from point β€˜B’ to β€˜A’ at a speed of 10 km/hr at 11:00 am. If they meet each other at 3:00 pm then find the distance between points β€˜A’ and β€˜B’.
    A 170 km Correct Answer Incorrect Answer
    B 120 km Correct Answer Incorrect Answer
    C 190 km Correct Answer Incorrect Answer
    D 180 km Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Distance covered by X in 2 hours = 25 Γ— 2 = 50 km Relative speed of X and Y = 25 + 10 = 35 km/hr Sum of distance covered by both in 4 hours = 35 Γ— 4 = 140 km Total distance between points β€˜A’ and β€˜B’ = 50 + 140 = 190 km
