The fastest trains are magnetically levitated above the rails to avoid friction (and are therefore called
MagLev trains...cool, huh?). The fastest trains travel about 250 km in a half an hour. What is their
average speed in km/hour?

• 250 km/hr
• 500 km/hr
• 125 km/hr

A cheetah travels 75 m in 3 s. What is her velocity over the interval?

• 225 m/s
• 25 m/s 
• 0.04 m/s

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
