Answer:
[tex]3\frac{1}{5}[/tex]brownies per hour
Step-by-step explanation:
Given parameters:
Number of brownies = [tex]\frac{4}{5}[/tex] of a dozen
Time taken = 3hrs
Unknown:
Average baking per hour = ?
Solution:
The average baking per hour;
This is a rate problem;
Average baking per hour = [tex]\frac{number of baking}{time}[/tex]
Number of brownies = [tex]\frac{4}{5}[/tex] x 12 = [tex]\frac{48}{5}[/tex]
Average baking per hour = [tex]\frac{48}{\frac{5}{3} }[/tex]
= [tex]\frac{48}{5} x \frac{1}{3}[/tex]
= [tex]\frac{16}{5}[/tex]
= 3[tex]\frac{1}{5}[/tex]brownies per hour
