1. Nascar driver, Jeff Gordon, has a car that is one of the fastest on the circuit. If it travels 600 miles in 4 hours, what is his cruising speed? 600miles 4 hours s= S= 150 miles/hour (mph)

2. The fastest car on Earth, a German-made Thrust SSC, would win every Nascar race in America. If it takes 0.5 hours (30 minutes) to travel 380 miles, what is its speed? 380 miles.5 hours s= S= 760 miles/hour (mph)

3. The fastest train on Earth, the TGV from France, can travel at faster speeds than trains in the United States. During a speed test, the train traveled 800 miles in 2.5 hours. What is its speed? 800miles 2.5 hours s= S= 320 miles/hour (mph)

4. Spirit of Australia, a hydroplane boat, made speed records by traveling 239 miles in 0.75 hours (45 minutes). What is its record- breaking speed? 239 miles.75 hours s= S= miles/hour (mph)

5. The fastest plane ever made, the Lockhead SR71, was able to travel 11,000 miles in 5 hours. How fast can the plane go? 11,000miles 5 hours s= S= 2,200 miles/hour (mph)
