    1/3 + 2/5 = 11/15....distance by foot and bus

    so, 4/15 of the journey is by car

    Then 4k/15 = 4

    Hence, k = 15

    so, total distance is 15 km

  • x/3 + 4 + 2x/5 = x

    1/3 + 4/x + 2/5 = 1

    5/15 + 4/x + 6/15 = 15/15

    11/15 + 4/x = 15/15

    4/x = 4/15

    x = 15

    1/3 + x + 2/5= 1

    (5 + x + 6)/15= 1

    11 + x= 15; x= 4

    x= 4 km is given, so total kilometers is 15.

    The 4 km as a fraction of his journey was 1 - 1/3 - 2/5 = 4/15

    The whole journey was 15 km, answer B
