## Homework Statement

I just translated this word problem:

The zone of a alga increases every 2 month about the factor 4. How many days does the alga needs to increse into the double? How many days ago has the alga been the half?

## Homework Equations

## The Attempt at a Solution

1.) The first question states

The algae increases by a factor of 4 every 60 days. how many "days" does the alga needs to increse into the double?

So I got 4x = 60 multiplyed 2

x = 30 days

2.) I don't understand the second question.

How many days ago has the alga been the half?

I would appreciate some help, thanks.
