Calculating Average Speed

Which information is needed to  determine  how fast a  truck  is traveling? 

• direction and  mass  
• distance  and time 
• size and  speed 
• time  and  weight  

A runner's times  for each section of a 400-meter race are shown below: 
Results from  400-meter Race
Section           Time  
1st 100  m      11 seconds
2nd 100 m      13 seconds
3rd 100 m       14 seconds
4th  100 m       14.5 seconds
Which best  describes the runner's motion over the course of  the 400-meter race? 

• The runner's speed increased. 
• The runner's speed decreased.  
• The runner's speed stayed the same.  
• The runner's direction stayed the same.  

A unusually fast zombie was chasing after Carl to eat him. What was the zombie’s speed at 6 seconds if he traveled 36 meters?

A dog can run 50 km in 5 days and a cat can run 15 km in 3 days. What is the difference in the two speeds? (Hint: You need to subtract!)

• 10 km/day
• 5 km/day

Car #1 that traveled 160 kilometers in 5 hours, and Car #2 traveled 140 kilometers in the same time. Which car traveled faster?

• Car #1
• Car #2
• Their speeds are equal.

What is speed?

• how far you go
• how much distance is covered over a period of time
• how fast you accelerate
• the change in the location of a object

To calculate average speed you _______ the distance traveled by the elapsed time.

• divide
• multiply
• square
• subtract
