Mr. Sonny's science class is calculating the average number of blinks per minute. Jan blinks 85 times in 5 minutes. What is her blinking rate, in blinks per minute?
To calculate the blinking rate, we divide the total number of blinks (85) by the total number of minutes (5):
Blinking rate = Total number of blinks / Total number of minutes
Blinking rate = 85 blinks / 5 minutes
Blinking rate = <<85/5=17>>17 blinks per minute
So Jan's blinking rate is 17 blinks per minute.
