On Tuesday it takes him 4 minutes. On Wednesday it takes him 3 minutes. On Thursday it takes him 4 minutes. Before Friday arrives he looks at his old way of getting dressed and sees that it was taking him 3 minutes on average to get dressed. How fast does he have to get dressed on Friday so his weekly average ties his old method? Let's think step by step and output the final answer after "####".

If it takes on average 3 minutes to get dressed, then it takes 15 minutes total on the school week because 5 x 3 = <<15=15>>15
Thus far this week it has taken him 13 minutes to get dressed because 2 + 4 + 3 + 4 = <<13=13>>13
To tie his previous method, he needs to take 2 minutes on Friday because 15 - 13 = <<15-13=2>>2
