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

### Instruction:
 Miriam spent 30 minutes doing laundry, 15 minutes cleaning the bathroom, a certain amount of time cleaning her room, and 40 minutes doing homework. If she spent a total of two hours on these tasks, how long, in minutes, did she spend cleaning her room?


### Response:
 Il y a 60 minutes dans une heure, donc Miriam a passé 60 * 2 = <<60*2=120>>120 minutes à faire des tâches.
Elle a passé 30 + 15 + 40 = <<30+15+40=85>>85 minutes à faire les trois tâches pour lesquelles elle avait des enregistrements de temps.
Elle a donc passé 120 - 85 = <<120-85=35>>35 minutes à nettoyer sa chambre.
