Well, the hint for this is that you can start a steak and take it off the grill and finish it later...
So you put two on to cook. After 5 min you flip one, take the second off the grill, and start the third. After 10 minutes, the first steak is done so you take it off, you flip the third one that's on the grill, and you put the second steak back on to finish its second side. This means that all three are done in 15 minutes.
Now I want steak.
