 The graph shows Ashley riding her bike to Maria's house. 
What was her average speed for the ENTIRE trip?

• 1600 m/min
• 200 m/min
• 160 m/min

Speed =

• distance / time
• time / distance
• distance * time

The graph below represents

• Speed
• Velocity
• Acceleration
• Deceleration

The graph represents

• Acceleration
• No motion
• Deceleration
• Constant Velocity

This is a velocity-time graph. What is the object doing in segment C?

• Speeding up

• Slowing down

• Constant Velocity

• Not moving

This graph demonstrates an object that is -

• Increasing speed
• At a constant speed
• Decreasing speed
• Stationary

A box sliding down an inclined plane attains a velocity of 27 m/s in 3 seconds from rest.  Find the acceleration.

• 30 m/s
• 24 m/s²
• 9 m/s²
• 81 km/hr
