Answer 1

Answer:

It will take C. 180 years to grow 720 millimeters.

Explanation:

The research shows that Mount Everest grows and average of 4 millimeters each year.

In order to calculate how many years it will take to grow 720 millimeters, we need to divide 720 millimeters by the average of 4 millimeters each year.

If we calculate it :

$\frac{720mm}{4\frac{mm}{year}}=180years$

We found out that it will take 180 years. Therefore, the correct option is C. 180
