A computers fan rotates 2000 times in 40 seconds. How do you find the unite rate in rotations per second?

Answer 1

#50# rotations per second

#2000" rotations"# in #40 " seconds"# could be written as #color(white)("XXX")(2000" rotations")/(40" seconds")#
#color(white)("XXX")=(cancel(200)^50cancel(0)" rotations")/(cancel(4)cancel(0)" seconds")#
#color(white)("XXX")=50 "rotations"/"second"#

Answer 2

To find the unit rate in rotations per second, divide the total number of rotations by the total time taken.

[ \text{Unit rate} = \frac{\text{Total number of rotations}}{\text{Total time taken}} ]

Given that the computer's fan rotates 2000 times in 40 seconds:

[ \text{Unit rate} = \frac{2000 \text{ rotations}}{40 \text{ seconds}} ]

[ \text{Unit rate} = \frac{2000}{40} ]

[ \text{Unit rate} = 50 \text{ rotations per second} ]

So, the unit rate of the fan's rotation is 50 rotations per second.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
