    • Question

      A person completes a journey in 300 minutes by train at a

      speed of 60 km/h. What should be his speed by bus to cover the same distance in 7 hours?
      A 60.60 km/h Correct Answer Incorrect Answer
      B 54.55 km/h Correct Answer Incorrect Answer
      C 42.86 km/h Correct Answer Incorrect Answer
      D 30.05 km/h Correct Answer Incorrect Answer

      Solution

      ATQ,

      When distance is constant,

      Time ∝ 1/Speed

      7 hours = 7 × 60 = 420 minutes

      (Speed of train) ÷ (Speed of bus) = 420 ÷ 300 = 7:5

      Speed of bus = (5/7) × 60 = 42.86 km/h
