      X started to run from point β€˜A’ to β€˜B’ at a

      speed of 28 km/hr at 9:00 am and Y started to run from point β€˜B’ to β€˜A’ at a speed of 12 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 206 km Correct Answer Incorrect Answer
      B 246 km Correct Answer Incorrect Answer
      C 210 km Correct Answer Incorrect Answer
      D 216 km Correct Answer Incorrect Answer

      Solution

      Distance covered by X in 2 hours = 28 Γ— 2 = 56 km Relative speed of X and Y = 28 + 12 = 40 km/hr Sum of distance covered by both in 4 hours = 40 Γ— 4 = 160 km Total distance between points β€˜A’ and β€˜B’ = 56 + 160 = 216 km
