Question

On average, I sleep about 7 hours and 45 minutes each day. So during one year, I sleep for 7.45x365=2719.25 or about 2700 hours. This calculation is not correct. What is the correct answer?

Answer 1

About 2,800 hours of sleep per year

Explanation:

Sleep per day= 7 hours 45 minutes

7 hours 45 minutes=465 minutes

Sleep per day =465 minutes

Sleep per year=365 days × 465 minutes

=169,725 minutes

There are 60 minutes in one hour

Divide 169,725 by 60 minutes

We have,

169,725/60

=2828.7500000 hours

Total sleep in a year is about 2,800 hours
