Unit 1 Linear Motion and Graph Test Review

How would you describe the motion and direction of the object in this distance vs time graph?

• The object is moving at a constant speed away from the origin.

• The object is accelerating.

• The object is moving at a constant speed towards the origin.

• The object is stationary.

A plane travels at an average speed of 600 kilometers per hour for 0.2 hours. How far does the plane travel? What formula do you need to use to solve this problem?

• s = d/t

• d = s x t

• t = d/s
