The number of cakes Mrs Darby can decorate in a 30-hour week is 22.5 cakes.

Number of cakes to decorate

  • 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
