To find the number of times an average person blinks in a year, we can multiply the number of blinks per hour by the number of hours in a day and then by the number of days in a year.
Number of blinks per hour = 15
Number of hours in a day = 24
Number of days in a year = 365
Total blinks in a year = 15 blinks/hour * 24 hours/day * 365 days/year
= 131,400 blinks/year
Writing this in scientific notation, we move the decimal point 4 places to the left:
= 1.314 × 10^5 blinks/year
Suppose an average person blinks 15 times per hour. How many times does an average person blink in a year? Write the answer in scientific notation (Hint: 1 year = 365 days, 1 day = 24 hours).
