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

### Instruction:
 Gunther needs to clean his apartment. It takes him 45 minutes to vacuum the carpets, 60 minutes to dust the furniture, 30 minutes to mop the floors in his kitchen, and 5 minutes to brush each cat, and he has three cats. If he has 3 hours of free time available, and he uses this time to clean his apartment, how many minutes of free time will he have left after he cleans the apartment?


### Response:
 Il faudra 5*3=<<5*3=15>>15 minutes pour brosser ses chats.
En tout, il faudra 45+60+30+15=<<45+60+30+15=150>>150 minutes pour nettoyer son appartement.
Il dispose de 180 minutes de temps libre, donc il lui restera 180-150=<<180-150=30>>30 minutes de temps libre.
