Constant Rate and Average Speed Problems

Which object travels at the greater average speed?

• Object 1, because it travels the greater distance per unit of time

• Object 1, because it travels the longer amount of time

• Object 1, because it travels the shorter amount of time

• Object 2, because it travels the shorter distance per unit of time

Two students record the distance they each traveled in 60 seconds in the data table shown. If the students continue at the same speed, which statement describes the total distance traveled after 90 seconds?

• Student 1 traveled 40 m, and student 2 traveled 20 m.

• Student 1 traveled 50 m, and student 2 traveled 30 m.

• Student 1 traveled 60 m, and student 2 traveled 30 m.

• Student 1 traveled 70 m, and student 2 traveled 25 m.

Select the times that the object is NOT moving according to the graph. (Could be more than one)

• 0-10 minutes.

• 10-20 minutes.

• 20-30 minutes.

• 30-40 minutes.

Which of these graphs represent a constant speed?

• 
• 
• 

A baseball is thrown a distance of 20 meters. What is its speed if it takes 0.5 seconds to cover the distance?

• 40 m/s

• 10 m/s

• 3 m/s

• 30 m/s

Calculate the average speed between 0 and 10 hours.

• 2 km/h

• 3 km/h

• 1 km/h

• 5 km/h

What is instantaneous speed?

• Overall speed of an object.

• Speed of an object at a specific moment.

• Speed that happens instantly.

• Distance v. time

What kind of speed does this graph represent?

• No speed.

• Constant Speed.

• Increasing speed.

• Decreasing speed.

Calculate the average speed

• 4.25 ft/min

• 0.24 ft/min

• 68 ft/min

• 21 ft/min

What happened during A to B point?

• not moving
• increasing speed at a constant rate
• moving at a constant speed
• moving at 10 m/s² acceleration
