Speed:
(i) It is a scalar quantity,
(ii) It can't be negative,
(iii) Speed is measured in units of distance.
Velocity:
(i) It is a vector quantity,
(ii) It can be negative,
(iii) Velocity is measured in units of displacement.

Answer 2

1....speed is a scalar quantity
velocity is a vector quantity
2...speed can never be negative
velocity can either be negative or positive
3....speed = distance/ time
velocity = displacement/ time
