There are 12 number of ski trails shown in the table.
<h3>What is an equation?</h3>An equation is an expression that shows the relationship between two or more variables and numbers.
From the table attached, we can see that there are only 12 different ski distances, that is there are 12 data's in the table, hence:
The total number of ski trails = 12

Step-by-step explanation:
If a variables varies jointly, we can just divide it by the other variables in relation to it.
For example, since p variables jointly as q and square of r, then
where k is a constant
First, let find k. Substitute p= 200
q= 2, and r=3.
Now, since we know our constant, let find p.
Q is 5, and r is 2.
