Answer 5

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.

15 blinks/hour × 24 hours/day × 365 days/year = 131,400 blinks/year

Writing it in scientific notation:
1.314 x 10^5 blinks/year
