Study the image below. The man traveled 3m to the right to reach point B, then turned left to walk northward to reach point C for 4m.  What is the total displacement?

• 3m

• 4m

• 5m

• 7m

Study the image below. The man traveled 3m to the right to reach point B, then turned left to walk northward to reach point C for 4m.  What is the total distance travelled?

• 3m

• 4m

• 5m

• 7m

What is the correct formula for computing for velocity?

"A car travelled 90 meters in 5 seconds. How fast is the car moving?"In this word problem, which given information shows the correct labelling?

• time = 90 meters, distance = 5 seconds

• time = 5 seconds, distance = 90 meters

• time = 90 meters, time = 5 seconds

• time = 5, distance = 90

A car travelled 90 meters in 5 seconds. How fast is the car moving?What is the correct answer to this problem?

• 180 m/s

• 18 m/s

• 90 m/s

• 5 m/s
