There can be many ways to solve this problem. Here, we will do this by thinking about units.
Let's say that Astrid can build
x
ships
xshipsx, start text, s, h, i, p, s, end text if she receives deliveries of wood for the maximum possible number of days, which is
100
days
100days100, start text, d, a, y, s, end text. How can we relate these two quantities with an equation?
100
days
⋅
y
ships
day
=
x
ships
100days⋅y
day
ships
=xships
So in order to find the number of ships
x
xx, we need to figure out the value of
y
yy, which is the rate of ships per day.

Hint #33 / 4
We can combine the following quantities:
4
tons
day
40
tons

=
4
40

=
0.1

Now we can plug that in the original equation:
100

ships
100days⋅0.1

Hint #44 / 4
In conclusion, assuming Astrid receives the maximum possible amount of wood, she can build
10
1010 ships.
