Breakfast is half of the time. So half of 40 is 20.
Dressing time = 1/4 of 40 which is 10
So 20+10 30 mini it’s are used so 40-30=10 minutes is left

Answer: 10 mins

Step-by-step explanation:
Half the time would be 20 mins and another quarter (or fourth) would be 10 mins adding these together you get 30

Then subtract 40-30 giving you 10
