Speed is different from velocity because

• Velocity has a direction
• Speed uses Distance /Time
• Velocity doesn't include time
• Velocity doesn't include distance

An object travels a distance of 12.8 m in 15 seconds. What is its average velocity?

• 15 m/s
• 12.8 m/s
• 0.85 m/s
• 1.17 m/s

A bike travels at a constant speed of 4 m/s for 5 seconds. How far does it go?

• 4 m
• 10 m
• 20 m
• 1.5 m

If a car accelerates from rest at a constant 5.5 m/s², how long will it take for the car to reach a velocity of 28 m/s?

• 5.1 s
• 33.5 s
• 56.1 s
• 154 s

The correct equation to calculate speed is

• distance divided by time
• time divided by distance
• distance x time
• distance divided by distance²
