On average, people blink 15–20 times per minute and breathe about 12–20 times. These rates vary based on activity or focus. Observing yourself for one minute gives a more personalized estimate.

class 6 Mathematics Chapter 3 Number Play solutions
a. In a typical minute, a person blinks 15–20 times and takes 12–20 breaths, depending on their activity level. Focused tasks like reading reduce blinking, while relaxed breathing maintains consistency. To estimate, observe yourself in a natural state for one minute. Record blinks and breaths separately, comparing your data with averages. Class discussions about variations (e.g., exercise versus rest) can enrich understanding of these biological rhythms and how they differ across individuals.
b. To estimate blinking and breathing in an hour, use average rates. People blink 15–20 times per minute, translating to 900–1,200 blinks in an hour. Breathing occurs 12–20 times per minute, totaling 720–1,200 breaths hourly. Rates vary during rest, focus, or physical activity. Estimations can be refined by tracking over shorter periods (e.g., 5 minutes) and scaling up. Comparing individual data highlights differences in physiology, adding context to class discussions about daily activities.
c. To estimate daily blinks and breaths, use hourly averages. People blink 900–1,200 times per hour, totaling 21,600–28,800 daily. Breathing averages 720–1,200 times hourly, adding up to 17,280–28,800 breaths each day. Variations occur due to activity levels, such as exercise, which increases breath rates, or focused tasks, which reduce blinking. Tracking shorter intervals and scaling up can refine estimates. Class discussions about differing rates encourage awareness of how lifestyle influences these fundamental biological processes.
