a) The location of FF after a time t is (186+8t)i + (44+12t)j.

Hint. If they collide then their i and j positions will be the same at the same time.

b) Add the time you found in a) onto 7:00am

c) Find the position of HW when the collision takes place. Find the distance between HW and the crash. the new speed of HW is 1.5 times the *Magnitude* of the old speed. You now know the distance it has to go and the speed it is going at so you can find when it arrives.
