Answer:
30 cakes.
Step-by-step explanation:
Given:
A cake decorator can decorate 6 cakes in 90 minutes.
Question asked:
At this rate,how many cakes could he decorate during his 8-hour workday if he takes two -15 minutes coffee breaks?
Solution:
Total number of hours, he work = 8 hours
1 hour = 60 minutes
8 hours = 60 [tex]\times[/tex] 8 = 480 minutes
Coffee break = 2 of 15 minutes, 15 + 15 = 30 minutes
Remaining working hour = 480 - 30 = 450 minutes
In 90 minutes, he decorate number of cakes = 6
In 1 minute, he decorates number of cakes = [tex]\frac{6}{90}[/tex]
In 450 minutes, he decorates number of cakes = [tex]\frac{6}{90}\times450=\frac{2700}{90} =30\ cakes[/tex]
Therefore, at this rate, he can decorate 30 cakes.
