To calculate the number of times an average person blinks in a year, we start with the following information:

  • The average person blinks 15 times per hour.
  • There are 24 hours in a day.
  • There are 365 days in a year.

First, we will calculate the number of blinks in one day:

\[ \text{Blinks in one day} = 15 \text{ blinks/hour} \times 24 \text{ hours/day} = 360 \text{ blinks/day} \]

Next, we calculate the total number of blinks in one year:

\[ \text{Blinks in one year} = 360 \text{ blinks/day} \times 365 \text{ days/year} = 131400 \text{ blinks/year} \]

Now, we convert 131400 into scientific notation:

\[ 131400 = 1.314 \times 10^5 \]

Therefore, the answer is:

1.314 × 10^5
