Q. Mr. Sonny's science class is calculating the average number of blinks per minute. Jan blinks

303

times in

3

minutes. What is her blinking rate, in blinks per minute?

Identify total blinks and time: Identify the total number of blinks and the total time in minutes. $\newline$ Jan blinks $303$ times in $3$ minutes.
Use rate calculation formula: Use the formula for calculating the rate, which is the number of events (blinks) divided by the time (minutes). $\newline$ Blinking rate = $\frac{\text{Total number of blinks}}{\text{Total number of minutes}}$
Plug in values for calculation: Plug in the values into the formula to calculate the blinking rate. $\newline$ Blinking rate = $303$ blinks $\div$ $3$ minutes
Perform division for blinking rate: Perform the division to find the blinking rate per minute. $\newline$ Blinking rate = $303 \div 3$ $\newline$ Blinking rate = $101$ blinks per minute
