Two travellers spend 6 hours walking along a level road, then up a hill, and then back home.
Their pace on the level road was 4 mph, up the hill was 3 mph, and down the hill was 6 mph.

Determine the total distance that they walked.


Solution to the Problem:


They walked a total of 24 miles.

Let x = distance walked on level ground one-way.
Let y= distanced walked up hill one-way.
Then set up an equation for the time that it took for the whole trip:


So, in six hours, they walked 12 miles out and 12 miles back, for a total of 24 miles.
