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.
