Question

a man travelled 3/5 of his journey by train, 1/4 by taxi, 1/8 by bus and the remaining 8km by foot. What is the length of his journey.

Answer 1

Find the fraction of the journey traveled by foot:

1 - 3/5 - 1/4 - 1/8 = 1/40

Find the total distance:

Man traveled 1/40 by foot

Man traveled 8 km by foot

1/40 of the journey = 8 km

40/40 of the journey = 8 x 40 = 320 km

Answer: The total journey is 320 km

Answer 2

8km =x-3x/5-x/4-x/8
8 =( 40x-24x-10x-5x)/40
x=320 km
