suppose a human blick 15 times an hour, how many times do you blink in a year?
To calculate the number of times a human blinks in a year, you need to determine the number of blinks per hour and multiply it by the number of hours in a day, days in a year, and finally divide by the number of blinks per minute. Typically, humans blink about 15 to 20 times per minute. Assuming a conservative average of 15 blinks per minute, the calculation would be as follows:
15 blinks/minute * 60 minutes/hour * 24 hours/day * 365 days/year
To calculate this, we multiply each component to find:
15 * 60 * 24 * 365 = 15,876,000 blinks/year
Therefore, a person blinks approximately 15,876,000 times in a year.
