Answer 1

To calculate how many times an average person blinks in a year, we can follow these steps:

1. Calculating the number of blinks per hour:

   • Average blinks per hour = 15

2. Calculating the number of hours in a year:

   • 1 year = 365 days
   • 1 day = 24 hours
   • Therefore, the total number of hours in a year is: \[ 365 \text{ days} \times 24 \text{ hours/day} = 8760 \text{ hours} \]

3. Calculating the total blinks in a year:

   • Total blinks in a year = blinks/hour × hours/year
   • Total blinks in a year = 15 blinks/hour × 8760 hours/year
   • Total blinks in a year = \( 15 \times 8760 = 131400 \)

4. Converting the total blinks into scientific notation:

   • \( 131400 = 1.314 \times 10^5 \)

So, the correct answer is:

1.314 × 10^5
