You have a start point 4 miles from the origin, when this story begins.

You then walk at a rate of speed for a specified time.

There really isn't much equationing (which isn't a word!) to be done here, since you know your speed and time:

Distance from start point =
4 miles
plus
3 miles per hour for 5 hours

s = 4 + 3 * 5
