**jim**, Saturday, October 24, 2009 at 5:45pmWe need a variable for the time. Let's call that t. And we can call the distance d.

At t = 0 (1pm) you are 150 miles away, and as t increases, the distance decreases, so we need to subtract some multiple of t from 150 as we go.

We need something that starts with

d =

since the distance is what we want to know, and the right hand side will be like

150 - something * t

Of course, technically, we'd need to limit the domain of t; otherwise, after 10 hours, we'll be negative miles away.
