Suppose an average person 15times per hour. how many times does an average person blink in a year? Write answer in scientific notation (1 point)
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, days in a year, and then apply scientific notation.
Blinks per hour = 15
Hours in a day = 24
Days in a year (assuming 365 days) = 365
Total blinks per year = Blinks per hour * Hours in a day * Days in a year
Total blinks per year = 15 * 24 * 365 = 131,400
Writing it in scientific notation, we have 1.314 × 10^5.
Therefore, an average person blinks approximately 1.314 × 10^5 times in a year.
