Answer 1

To calculate the number of times an average person blinks in a year, we can follow these steps:

1. Calculate the number of hours in a year: \[ \text{Number of hours in a year} = 365 \text{ days/year} \times 24 \text{ hours/day} = 8760 \text{ hours/year} \]

2. Calculate the number of blinks in a year: \[ \text{Number of blinks in a year} = 15 \text{ blinks/hour} \times 8760 \text{ hours/year} \] \[ = 15 \times 8760 = 131400 \text{ blinks} \]

3. Convert the total blinks into scientific notation: \[ 131400 = 1.314 \times 10^5 \]

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

\[ \boxed{1.314 \times 10^5} \]
