Suppose an average person blinks 15 times per hour how many time does the average person blink in a year write the answer in scientific notation
To calculate the number of times an average person blinks in a year, we need to multiply the blinks per hour by the number of hours in a year.
15 blinks/hour * 24 hours/day * 365.25 days/year = 131,490 blinks/year
The answer in scientific notation is 1.3149 × 10^5 blinks/year.
To calculate the number of times an average person blinks in a year, we need to multiply the number of times they blink in an hour by the number of hours in a day, the number of days in a year, and finally express the answer in scientific notation.
Average number of times a person blinks per hour = 15 times
Number of hours in a day = 24 hours
Number of days in a year = 365 days
Now let's calculate:
15 times per hour × 24 hours per day × 365 days per year = 131,400 times per year
In scientific notation, this can be written as:
1.314 × 10^5 times per year
To find the number of times an average person blinks in a year, we can use the following steps:
1. Convert the number of blinks per hour to blinks per year:
- The average person blinks 15 times per hour.
- In a day, there are 24 hours, so the person blinks 15 * 24 = 360 times per day.
- In a year, there are 365 days, so the person blinks 360 * 365 = 131,400 times per year.
2. Write the answer in scientific notation:
- Scientific notation represents a number as a product of a decimal number between 1 and 10, and a power of 10.
- In this case, 131,400 can be written as 1.314 × 10^5, where the decimal part is 1.314 and the exponent is 5.
Therefore, the average person blinks approximately 1.314 × 10^5 times in a year.
