Identify the two pieces of information you need to know the velocity of an object

Velocity has direction
speed does not

ex
if you are traveling north at 4 miles per hour then
speed=4 miles per hour'
velocity=4 miles per hour north

so you need 3 pieces of info
1. distance convered
2. time it took you
3. direction you are traveling

if you think that velocity is speed then you need
1. distance covered
2. time it took you
