To find the number of times an average person blinks in a year, we need to multiply the number of blinks per hour by the number of hours in a day (24) and the number of days in a year (365).
15 blinks/hour x 24 hours/day x 365 days/year = 131,400 blinks/year
Since we need to write the answer in scientific notation, we should express it as 1.314 x 10^5
Therefore, the correct answer is 3. 1.314 x 10^5
suppose tan 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: 1year = 365 days, 1 day = 24 hours)
1. 1.314 x 10^-5
2. 1.314 x 10^-4
3. 1.314 x 10^5
4. 1.314 x 10^4
