Velocity is defined as the rate of change of displacement and includes both a magnitude and a direction. Among the provided options, the quantities are:
a. 3 g/L in weight - This is a density (weight per volume), not a velocity.
b. 25 m/s - This is a speed but does not have a direction, so it is not a velocity.
c. 10 km/hr eastward - This has both a magnitude (10 km/hr) and a direction (eastward), making it a velocity.
d. 15 m/s² - This is an acceleration (change in velocity over time), not a velocity.
Therefore, the correct answer is c. 10 km/hr eastward.
