Question

1. Delia brushes her teeth 1/6 hour each day.

Answer 1

Answer:

PART A: 28 hours, PART B: 16800 minutes

Step-by-step 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 = $\frac{1}{6}$ × 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 = $\frac{1}{6}$× 100800

Number of hours that Delia brushes her teeth = 16800 minutes

Hence, the correct answer is 16800 minutes
