If Bill drives 45 MPH and Jim leaves 2 hours later and drives 75 MPH and they both maintain constant speed, how long will Jim travel before passing Bill?

• Math -

the key point is that when Jim passes Bill, at that moment they will have traveled the same distance.

Distance covered by Bill = 45t
Distance covered by Jim = 75(t-2)

equate those two expressions and solve for t
