Travelling along Geometry

Geometry Level 1

Suppose that you are driving to Seattle at constant speed, and notice that after you have been traveling for $$1\ hour$$ (i.e., $$t_1 = 1$$), you pass a sign saying it is $$110\ miles$$ to Seattle, and after driving another $$\frac { 1 }{ 2 } \ hour$$, you again pass a sign saying it is $$85\ miles$$ to Seattle. Find the Speed $$s$$ at which you're travelling, Total Distance $$d$$, and Total Time $$t$$ of the trip.
