Question
Suppose an average person blinks 15 times per hour how many times does an average person blink in a year? Write the answer in scientific notation hint one year equals 365 days one day equals 24 hours so would the answer be 1.314×10 negative power of four or 1.314×10 power of 50 1.314×10 four power or 1.314×10 with the power of -5

To find out how many times an average person blinks in a year, you can follow these steps:
1. **Calculate the number of blinks per day**:
- Blinks per hour = 15
- Hours per day = 24
- Blinks per day = 15 blinks/hour × 24 hours/day = 360 blinks/day
2. **Calculate the number of blinks in a year**:
- Days per year = 365
- Blinks per year = 360 blinks/day × 365 days/year = 131400 blinks/year
3. **Express the result in scientific notation**:
- 131400 can be written as \( 1.314 \times 10^5 \) (since 131400 = 1.314 * 100000).
So, the correct answer is \( 1.314 \times 10^5 \).
