  • Question
  • A student goes to his school from his house walking at 4 km/h and reaches his school 10 min late. Next day, starting at the same time he walks as 6 km/h and reaches his school 5 min earlier than the scheduled time. Find the distance between school and home?


  • Options
  • A. 2 km
  • B. 3 km
  • C. 4 km
  • D. 5 km

  • Correct Answer
  • 3 km 

    Explanation

    Let the distance be x km.
    ? Time = Distance/speed
    1st day time taken = x/4 h
    2nd day time taken = x/6 h
    Difference in time = (x/4 - x/6) h
    Actual difference between these two times = 15 min = 1/4 h
    ? x/4 - x/6 = 1/4 ? (3x - 2x)/12 = 1/4
    ? x = 3 km
