      A boat moves with a downstream speed that is 8 km/hr more

      than its upstream speed. If the boat’s speed in still water exceeds the current’s speed by 12 km/hr, calculate the downstream speed of the boat.
      A 31 km/hr Correct Answer Incorrect Answer
      B 32 km/hr Correct Answer Incorrect Answer
      C 24 km/hr Correct Answer Incorrect Answer
      D 20 km/hr Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      ATQ,

      Speed of the current = 8 / 2 = 4 km/hr

      Speed of the boat in still water = 4 + 12 = 16 km/hr

      Downstream speed of the boat = 16 + 4 = 20 km/hr
