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).(1
5.25 x 10^6 times
To calculate the number of times an average person blinks in a year:
15 blinks per hour x 24 hours per day = 360 blinks per day
360 blinks per day x 365 days per year = 131,400 blinks per year
Writing this number in scientific notation:
131,400 = 1.314 x 10^5
Therefore, an average person blinks approximately 1.314 x 10^5 times in a year.
