Which expression is dimensionally consistent with anexpression that would yield a value for time-1? (v is velocity, x is distance, and t istime)
a. v/x
b. v2/x
c. x/t
d. v2/t
e. x/v

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 :

               Option A is correct
