If 2cm is done 3 years then how long will it get to 100cm

To solve this problem, we can use proportions.

Let x represent the time it will take to reach 100cm.

We have the following proportion:

2cm / 3 years = 100cm / x years

Simplifying this proportion, we get:

2/3 = 100/x

To find x, we need to cross multiply:

2x = 100 * 3

2x = 300

Dividing both sides by 2:

x = 150

Therefore, it will take 150 years to reach 100cm.
