• Charlie

How long did one of the runner's rest?

• 8 seconds
• 13 seconds
• 5 seconds
• 50 seconds

What does this graph represent?

• Constant Speed
• Acceleration
• Not moving

Describe the motion in the graph:

• Constant Speed (positive slope)

• Stopped (at rest)

• Acceleration (increasing speed)

• Return Home (negative slope)

What is the equation to calculate speed?

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