On a trip across the Grand Canyon in Arizona, a group traveled one-third
the distance by mule, 6 kilometers by boat, and one-half the distance by foot.
How long was the trip?
:
Let d = the total distance of the trip
:
d = Mule + boat + foot
d = d + 6 + d
multiply by 6 to clear the denominators, results
6d = 2d + 6(6) + 3d
6d = 5d + 36
6d - 5d = 36
d = 36 km trip
:
:
Check; find the distance at each stage of the trip
(36) = 12
(36) = 18
boat dist = 6
---------------------
total distance: 36
