Answer:
The equation of variation is a t = k or a = 
Step-by-step explanation:
Inverse variation is a relationship between two variables which can be modeled by an equation where the product of two variables is equal to a constant, and this constant is called constant of proportionality
Ex: if y varies inversely with x ⇒ y ∝
The equation is y =
<em>OR</em> yx = k, where k is the constant of proportionality
∵ a varies inversely as t
∴ a ∝ 
- Put them in the equation by using k the constant of proportionality
∴ a = 
- Multiply both sides by t
∴ a t = k
The equation of variation is a t = k or a =
