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

### Instruction:
Fiona completed 36 math questions in an hour. Shirley was able to complete twice as many math questions within that same time, and Kiana completed half of the sum of Fiona and Shirley's math questions. If they each did the same number of questions the following hour, how many math questions did all three girls complete in 2 hours?

### Response:
 Shirley alimaliza maswali 2 x 36 = <<2*36=72>>72.
Jumla ya maswali ya Fiona na Shirley ni 72 + 36 = <<72+36=108>>108 maswali.
Kiana alimaliza 1/2 x 108 maswali = <<1/2*108=54>>54 maswali.
Kwa saa moja, walimaliza 108 + 54 = <<108+54=162>>162 maswali.
Kwa masaa 2, walimaliza 162 x 2 = <<162*2=324>>324 maswali.
