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

### Instruction:
Joan has 2 hours to get all her music practice done. She spends 30 minutes on the piano, 25 minutes writing music on her computer, and 38 minutes reading about the history of the piano. Her final work is to use a special finger exerciser. How much time does she have left to use this?

### Response:
 Joan ana dakika 120 za kufanya mazoezi kwa sababu 2 mara 60 ni sawa na <<2*60=120>>120.
Ameshatumia dakika 93 kwa sababu 30 plus 25 plus 38 ni sawa na <<30+25+38=93>>93.
Ana dakika 27 za kutumia kwenye mazoezi ya vidole kwa sababu 120 minus 93 ni sawa na <<120-93=27>>27.
