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)
To find out how many times an average person blinks in a year, we first need to find out how many times they blink in a day. They blink 15 times per hour, so in a day (24 hours), they blink 15 * 24 = 360 times.
Now, to find out how many times they blink in a year, we multiply the number of blinks in a day by the number of days in a year (365):
360 * 365 = 131,400
The answer, using scientific notation, is 1.314 x 10^5.
