Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Osborn is testing a new way to get dressed in the morning on school days so he goes faster and can get up later. He tracks his time for the week and on Monday is takes him 2 minutes. 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?

### Response:
 Ikiwa inachukua wastani wa dakika 3 kuvaa, basi inachukua dakika 15 jumla kwa wiki ya shule kwa sababu 5 x 3 = <<15=15>>15
Mpaka sasa wiki hii imemchukua dakika 13 kuvaa kwa sababu 2 + 4 + 3 + 4 = <<2+4+3+4=13>>13
Ili kufanana na njia yake ya zamani, anahitaji kutumia dakika 2 Ijumaa kwa sababu 15 - 13 = <<15-13=2>>2
