To find the number of times an average person blinks in a year, we first need to calculate the number of blinks in a day, and then multiply that by the number of days in a year.
Number of blinks in a day = 15 blinks/hour × 24 hours/day = 360 blinks/day
Number of blinks in a year = 360 blinks/day × 365 days/year = 131,400 blinks/year
Written in scientific notation, this is:
1.314 × 10^5
The number 5.9×10^5 in decimal notation is:
