Asked by Jessica

If the change in position Dx is related to velocity v (with units of m/s) in the equation Dx = Av, the constant A has which dimension?

a) m/s2
b) m
c) s
d) m2

I'm not sure how to eliminate the seconds from the velocity. Thanks in advance for any help!

velocity * time = change in location (Dx)
Therefore the answer is c) seconds

Quantities must have different units before they can be added or subtracted.
