Tourists were on a hiking trip for three days. On the first day, they hiked 1/8 of the trail. On the second day they hiked 4/7 of the remaining trail. On the third day they hiked 1/3 of the remaining trail and the last 8 km. How many km is the whole trail?





Answered by Reiny
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
day3 :
(1/3)(3/8)x + 8 = x
x/8 + 8 = x
times 8
x + 64 = 8x
7x = 64

the trail is 64/7 km

check:
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
= 64/7
yeahhh!
