Answer 2

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 year.

Number of blinks per hour = 15
Number of hours in a year = 365 days/year * 24 hours/day = 8760 hours/year

Therefore, the number of times an average person blinks in a year is:

15 blinks/hour * 8760 hours/year = 131,400 blinks/year

Now we can write the answer in scientific notation:
1.314 × 10^5
