Last week ms. simpson worked 28 hours. she stocked shelves for 45 minutes each hour for 14 of those hours the rest of the time she worked in customer service. how many minutes last week did ms. simpson work in customer service? (hint: 1 hour=60 minutes

Hi. 45 minutes out of 60 min is 3/4 of an hour. multiply 3/4 by 14 and you have 10 1/2 hours. 28 hrs - 10 1/2 is 17 1/2 hours. multiply by 60 and you have:   

1050 min.

1050 minutes or 17.5 hours because she worked 10.5 out of the 28 hours, stocking shelves and the rest working in customer service therefore she worked 28 - 10.5 hours in costumer service which is 17.5 hours. As you said there are 60 minutes in an hour so you multiply 17 by 60 = 1020 + 1/2 of 60 = 30 minutes. If you add 1020 and 30 you would get 1050 hours.
