      Question

      The speed of two cars A and B are in the ratio of 15:19

      respectively. Car A travels 16 km less than the car B in the same time duration. What was the distance (in km) travelled by the car B during that time?
      A 68 km Correct Answer Incorrect Answer
      B 57 km Correct Answer Incorrect Answer
      C 85 km Correct Answer Incorrect Answer
      D 76 km Correct Answer Incorrect Answer
      E None of these Correct Answer Incorrect Answer

      Solution

      Let the speed of car A = 15x km/h and the speed of car B = 19x km/h. Here the time is constant. According to question, => 19x – 15x = 16 => 4x = 16 => x = 4 Distance travelled by car B = 19 × 4 = 76 km
