To find the number of times an average person blinks in a year, we can multiply the number of blinks per hour by the number of hours in a day and then by the number of days in a year.
15 blinks/hour × 24 hours/day × 365 days/year = 131,400 blinks/year
Writing it in scientific notation:
1.314 x 10^5 blinks/year
The number 7.3×10^−8 in decimal notation is 0.000000073.
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: 1 year = 365 days, 1 day = 24 hours).(1 point)
