Question

Dr. Peterson works about 178 hours each month. Which of the following is the best estimate of the number of hours she works in a year?

Answer 1

Option B.

Explanation:

Dr. Peterson works about 178 hours each month.

There are 12 months in one year.

So Dr. Peterson works in a year = 178 × 12 = 2,136 hours

We will go through all the options to find which is the closest to the answer.

Option A : 200 × 20 = 4,000 hours

Option B : 180 × 10 = 1,800 hours

Option C : 100 × 12 = 1,200 hours

Option D : 100 × 10 = 1,000 hours

Therefore, Option B is the best estimate of the number of the hours she works in a year.
