      A vehicle was scheduled to complete a 360 km journey in

      6 hours. For the initial 4 hours, it maintained a steady speed of 56 km/h. At what minimum speed must the vehicle travel for the remaining distance to ensure it arrives on schedule?
      A 80 km/h Correct Answer Incorrect Answer
      B 64 km/h Correct Answer Incorrect Answer
      C 66 km/h Correct Answer Incorrect Answer
      D 72 km/h Correct Answer Incorrect Answer
      E 68 km/h Correct Answer Incorrect Answer

      Solution

      Distance covered by the car in the first 4 hours = 56 X 4 = 224 km Remaining distance = 360 - 224 = 136 km Remaining time = 6 - 4 = 2 hours So, minimum speed required to car the distance on time = 136 ÷ 2 = 68 km/h Hence, option e.
