given
distance- 200km
time-5 hours
speed- distance/time
200/5
40km/hr
Divide distance by time for speed
Divide speed by distance for time
Multiply speed and time for distance
Those are...
You need the distance that something traveled in a given amount of time. The velocity is that distance divided by the time. v=d/t It is a very useful number because it tells you how far something...
Velocity = Delta-x / Delta-t, where x is position, t is time, and "Delta" is the "Change in" operator. Velocity is a vector, so I probably should have written x as x, or x-arrow, or some other...
