  • Question
  • Amit start from a point A and walks to another point B and then return from B to A by his car and thus takes a total time of 6 h 45 min. If he had driven both ways in his car, he would have taken 2 h less. How long would it take for him to walk both ways?


  • Options
  • A. 7 h 45 min
  • B. 8 h 15 min
  • C. 8 h 30 min
  • D. 8 h 45 min

  • Correct Answer
  • 8 h 45 min 

    Explanation

    Let w be the time taken in one way by walking and c be the time taken in one way by car.
    Now, according to the question,
    In first case, w + c = 6 h 45 min
    or
    2w + 2c = 13 h 30 min ..(i)
    In second case, 2c = 4 h 45 min ....(ii)
    From Eqs. (i) and (ii), we get
    2w + 2c = 13 h 30 min
    ? 2w + 4h 45 min = 13 h 30 min
    ? 2w = 13 h 30 min - 4 h 45 min
    ? 2w = 8 h 45 min
    ? If he walks both ways, then time taken = 8 h 45 min
