kramer

Answer:

64/7 i think

Step-by-step explanation:

whole trip ---- x km


day1 , hiked 1/8 of train, leaving (7/8)x

day 2 , hiked 4/7 of (7/8)x leaving

(3/7)(7/8)x or (3/8)x to be hiked

day 1 they hiked (1/8)(64/7)

leaving (7/8)(64/7) = 8 km

day2, hiked 4/7 of remaining, leaving

(3/7)(8) or 24/7 km

day 3

(1/3)(24/7) + 8
