To calculate the number of times an average person blinks in a year, we can follow these steps:
-
Calculate the total number of hours in a year: \[ 1 \text{ year} = 365 \text{ days} \times 24 \text{ hours/day} = 8760 \text{ hours} \]
-
Calculate the total number of blinks in a year: \[ \text{Total blinks} = 15 \text{ blinks/hour} \times 8760 \text{ hours} = 131400 \text{ blinks} \]
-
Now, we need to convert 131400 into scientific notation: \[ 131400 = 1.314 \times 10^5 \]
So, the answer is: \[ \boxed{1.314 \times 10^5} \]
