Speed is a:

• rate

• meter

• unit

• object

Distance divided by time is the formula to find:

• time

• speed

• distance

• reference point

The total distance you rode divided by the total time it took is the:

• rate

• speed

• average speed

• time

How would you find the speed of a person who walked 12 meters in 6 seconds?

• Speed = 12m / 6 sec

• Speed =

  6 sec x 12 m

• Speed =

  6 sec / 12 m

• Time = 6 sec / 12m

The speed in a given direction is called:

• reference point

• velocity

• motion

• speed
