The number of cakes Mrs Darby can decorate in a 30-hour week is 22.5 cakes.
<h3> Number of cakes to decorate</h3>
- Time taken to decorate a cake = 1 1/3 hours
- Total time for decoration per week = 30 hours
Time conversion
1 hour = 60 minutes
1 1/3 hours = 60 × 1 1/3
= 60 × 4/3
= 240/3
= 80 minutes
30 hours = 30 × 60
= 1800 minutes
Number of cakes decorated = 1800 / 80
= 22.5 cakes
