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?
There are 30+15+40=<<30+15+40=85>>85 minutes accounted for.
She spent 2*60=<<2*60=120>>120 minutes.
She spent 120-85=<<120-85=35>>35 minutes cleaning her room.
