Respuesta :

v = m/s
v = 2000m/400s
v = 5m/s

Answer:

5m/s

Explanation:

Velocity is the rate of change of distance with time in a given direction i.e velocity is the ratio of displacements with time. it is measured in m/s. Velocity is a vector quantity as it has both magnitude and direction unlike speed though both have the same units.

Velocity = 2000m/400s

= 5m/s
