I think I know how to do it
Your equation is:
P₁V₁ = P₂V₂
You Know:
Initial:
P₁ = 84 Pa
V₁ = 336 L
New:
P₂ = ?
V₂ = 216L
Plug this into the equation:
P₁V₁ = P₂V₂
(84 Pa)(336 L) = P₂(216 L) Divide 216 on both sides

130.6666666 = P₂
(if your doing significant figures, you have 2 sig figs)
130 Pa = P₂
Answer:
The snail will travel 11.75 ft in 5 minutes.
Rule= S(t) = 2.35 t
Explanation:
Since the snail is moving at 2.35 ft per minute, all you have to do is multiply 2.35 by 5 and that's how you get 11.75.
The Rule is the equation that could be used to solve the problem. S represents the snail, and t is how much time the snail travels. To solve from the rule, all you have to do is replace the t in the parenthesis and at the end with a 5 to represent the 5 minutes the snail travels.
Hope this makes sense to you.
