Mr. Sonny's science class is calculating the average number of blinks per minute. Jan blinks 105 times in 7 minutes. What is her blinking rate, in blinks per minute?

Answer 1

To calculate the blinking rate, we need to divide the total number of blinks by the total number of minutes.

Jan blinked 105 times in 7 minutes.

The blinking rate is 105 blinks / 7 minutes = <<105/7=15>>15 blinks per minute. Answer: \boxed{15}.
