Answer:
This is a simple math problem, and for that, the rule of three can be used.
Explanation:
The rule of three in this case will work like this, we have three informations on the question, and we're searching for the fourth one, so by that let's do the rule of three below:
1,25cm - 1 year
812,5cm - X
After that we multiply 1,25 with X and 1 with 812,5, the result is this:
1,25X = 812,5
X = 812,5/1,25
X = 650
So the answer to the question is 650 years to widen another 812,5 centimeters.
