Answer 2

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

Step-by-step 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 :
