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

### Instruction:
Carly is making burgers for a neighborhood BBQ. Each burger needs to be cooked for 4 minutes on each side. Carly can fit 5 burgers on the grill at once. If half her 30 guests want 2 burgers and the other half each want 1, how long will it take Carly to cook all the burgers?

### Response:
 Kwanza tafuta idadi ya jumla ya mikate ambayo nusu ya wageni wanataka: 2 mikate/mgeni * 15 wageni = <<2*15=30>>30 mikate
Kisha ongeza mikate 15 kwa nusu nyingine ya wageni ili kupata idadi ya jumla ya mikate: 30 mikate + 15 mikate = <<30+15=45>>45 mikate
Kisha gawanya idadi ya jumla ya mikate na idadi ya mikate Carly anaweza kupika kwa wakati mmoja ili kupata idadi ya vipindi vya kupikia: 45 mikate / 5 mikate/kipindi = <<45/5=9>>9 vipindi
Kisha multiply idadi ya upande kwa kila burger na idadi ya vipindi vya kupikia ili kupata muda wa jumla wa kupikia kwa kila burger: 4 dakika/upande * 2 pande * 9 vipindi = <<4*2*9=72>>72 dakika
