<h2>Option A is the correct answer.</h2>
Explanation:
Here we need to find an expression that would yield a value for time⁻¹
We know that
Velocity = Displacement ÷ Time
v = x/t
Option A :
![\frac{v}{x}=\frac{\frac{x}{t}}{x}=\frac{1}{t}=t^{-1}](https://tex.z-dn.net/?f=%5Cfrac%7Bv%7D%7Bx%7D%3D%5Cfrac%7B%5Cfrac%7Bx%7D%7Bt%7D%7D%7Bx%7D%3D%5Cfrac%7B1%7D%7Bt%7D%3Dt%5E%7B-1%7D)
Option A is correct
Option B :
![\frac{v^2}{x}=\frac{\frac{x^2}{t^2}}{x}=\frac{x}{t^2}](https://tex.z-dn.net/?f=%5Cfrac%7Bv%5E2%7D%7Bx%7D%3D%5Cfrac%7B%5Cfrac%7Bx%5E2%7D%7Bt%5E2%7D%7D%7Bx%7D%3D%5Cfrac%7Bx%7D%7Bt%5E2%7D)
Option B is not correct
Option C :
![\frac{x}{t}](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7Bt%7D)
Option C is not correct
Option D :
![\frac{v^2}{t}=\frac{\frac{x^2}{t^2}}{t}=\frac{x^2}{t^3}](https://tex.z-dn.net/?f=%5Cfrac%7Bv%5E2%7D%7Bt%7D%3D%5Cfrac%7B%5Cfrac%7Bx%5E2%7D%7Bt%5E2%7D%7D%7Bt%7D%3D%5Cfrac%7Bx%5E2%7D%7Bt%5E3%7D)
Option D is not correct
Option E :
![\frac{x}{v}=\frac{x}{\frac{x}{t}}=t](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7Bv%7D%3D%5Cfrac%7Bx%7D%7B%5Cfrac%7Bx%7D%7Bt%7D%7D%3Dt)
Option E is not correct
Option A is the correct answer.
