Joe and his family traveled up Interstate 71 from Cincinnati to Cleveland. They left at 8 in the morning, stopped at a rest area just north of Columbus, and arrived at their destination at 2 pm. They traveled a total of 240 miles. Having traveled 240 miles in 6 hours, Joe calculated that they traveled 40 mph northwest.

What best describes what the 40 mph NW represents?

• Joe’s average speed

• Joe’s constant speed

• Joe’s average velocity

• Joe’s constant velocity

Based on the graph, which best describes the motion of the car?

• The car is motionless.

• The car’s motion is constant through time.

• The car is experiencing positive acceleration.

• The car is experiencing negative acceleration.

Based on the graph, what can you say about the truck’s motion at 4 seconds?

• The truck is traveling downhill.

• The truck’s average speed is 20 m/s.

• The truck has an instantaneous speed of 20 m/s.

• The truck’s speed is the same as it is throughout because the line has the same slope.
