Measure and Graph Distance and Speed as a Function of Time

What is the equation to calculate speed?

• speed = distance/time
• speed = time/distance
• speed = time x distance 
• speed = speed/time 

The picture of the position vs. time graph shows an object that is...

• accelerating/speeding up
• moving at a constant speed 
• not moving 
• accelerating/slowing down. 

At what point is the speed the greatest?

• C-D

• B-C

• A-B

• D-E
