Answer 2

Older children and adults, when resting, usually breathe about 12-20 times per minute. Over the course of a day, that adds up to 17,000-30,000 breaths per day — or more! Those average breathing rates are for when you're at rest. When you exercise — or even walk around the house or school — your breathing rate goes up.
