Question

The breathing rate of an adult at exercise and rest respectively will be

• A. 25 and 18 times per minute
• B. 18 and 25 times per minute
• C. 35 and 28 times per minute
• D. 28 and 35 times per minute

Answer 1

The correct option is A 25 and 18 times per minute

Respiratory rate or breathing rate of a person increases with increasing physical activity. The normal breathing rate of an adult is 12-20 breathes per minute. But it is counted to be more than 20 breathes during exercise and less than 20 breathes at rest of the body.

So the correct answer is '25 and 18 times per minute'.
