If a student knows a ship traveled 300 meters straight north at 10 km/h, what else does the student know?

a. velocity

b. acceleration

c. average acceleration

d. instantaneous speed

I think the correct answer would be a. If a students that a ship traveled 300 m north at 10 km/h, then the student knows the velocity of the sheep. Velocity is a vector quantity which means it has direction. In this case, the velocity is 10 km/h, north direction.
