Answer
Find out the unit rate .
To prove
As given
Kevin entered a pie eating contest.
Kevin ate 4 pies in 132 seconds.
Definition of unit rate.
Unit Rate is the ratio of two measurements in which the second term is 1.
Thus
4 pies = 132 seconds
Now calculate for time for the eating 1 pie.
\(Time\ for\ the\ eating\ one\ pie = \frac{132}{4}\)
= 33 seconds
Therefore Time for the eating 1 pie is 33 second.
