Answer 1

PART A: 28 hours, PART B: 16800 minutes

Explanation:

Delia Brushes her teeth = 1/6 hour

PART A

Total Week= 1 week

Total number of days in a week= 7 days

Total number of hours in a day= 24 hours

Total number of hours in a week= 24× 7 hours

Total number of hours in a week= 168 hours

Number of hours that Delia brushes her teeth =
`(1)/(6)` × 168 hours

Number of hours that Delia brushes her teeth = 28 hours

Hence, the correct answer is 28 hours

PART B

Total number of days in a week= 7 days

Total number of hours in a week= 168 hours

Total number of minutes in a week= 168 × 60

Total number of hours in a week= 100800 Minutes

Number of minutes that Delia brushes her teeth =
`(1)/(6)`× 100800

Number of hours that Delia brushes her teeth = 16800 minutes

Hence, the correct answer is 16800 minutes
