### Velocity Practice Problems

 Velocity Practice Problems Remember that speed is how fast an object is moving. Speed is a scalar quantity. Velocity is a measure of speed in a particular direction. Velocity is a vector quantity. The formula is:    speed = distance/time.  Remember when solving for time:  t = d/s Remember when solving for distance:  d = s X t You may use scratch paper, a calculator and a pencil to help answer the following questions. Select the best answer from the choices.
