Question

During a camping trip, a group went one -third of the total distance by boat, 10km by foot and One – sixth of it by riding horses. Find the total distance of the trip.

Answer 1

Answer: d = 20

Explanation:

Let d be the total distance

d = (1/3)d + 10 + (1/6)d
(6/6)d = (2/6)d + 60/6 + (1/6)d
6d = 2d + 60 + d
6d = 3d + 60
3d = 60
d = 60/3 = 20
