Jordan and his three best friends are on a relay team. His relay team will run a race, where the first runner runs a lap, then the second, then the third, then the fourth.

Jordan is the fastest so he will run the fourth lap. Ed will run the third lap.  How many different orders can the four team members run, assuming that Jordan runs the fourth lap and Ed runs the third lap?
