hi friend,
<>the given quantity is velocity.because speed is a scalar quantity .it has only magnitude but not direction..and velocity is a vector quantity ,it depends on magnitude as well as direction.. so the given quantity is velocity.
<>since given quantity is -20m/s ,it shows magnitude as well as direction.
I hope this will help u ;)

that is why it is speed... velocity needs direction not speed

A quantity us measured is-20m's
---------------------------------------
m/s is the unit of both speed and velocity
in order to differentiate between the two , we need to understand their definitions
speed depends on magnitude but not on direction whereas the velocity depends on both
as it is given -20m/'s
there is a negative sign which indicates the direction , hence it is velocity
