Question

magine that Amy counted 60 numbers per minute and continued to count nonstop until she reached 19,000. Determine a reasonable estimate of the number of hours it would take Amy to complete the counting. It will take Amy approximately (Type a whole number.) hours to count to 19,000.

Answer 1

It will take Amy approximately 5.28 hours to count to 19,000.

Explanation:

The first step to solve this problem is finding how many minutes it takes for Amy to count to 19,000. In each minute, she counts 60 numbers. So

1 minutes - 60 numbers

x minutes - 19,000 numbers

`60x = 19,000`

`x = (19,000)/(60)`

`x = 316.7 minutes`

It is going to take 316.7 minutes for Amy to count to 19,000. How many hours are 316.7 minutes? Each hour has 60 minutes, so:

1 hour - 60 minutes

x hours - 316.7 minutes

`60x = 316.7`

`x = (316.7)/(60)`

`x = 5.28`

It will take Amy approximately 5.28 hours to count to 19,000.
