Name: Date: Period: Round answers to the nearest tenth (one decimal place)! 1. A Nascar driver has a car that is one of the fastest on the circuit. It travels 965.6 km (600 miles) in 4 hours. 60 min 60sec a. 965.6 km = m b. 4 hours = s 1 hour 1min c. What is the car’s average speed? G U E S S 2. The fastest street car on Earth, a Bugatti Veyron, would win every Nascar race in America. It takes 2.38 hours to travel the same 965.6 km (600 miles). a. 2.38 hours = s b. What is the car’s average speed? G U E S S 3. The fastest of all cars on Earth is the British jet car the Trust SSC. If that car would race, it would travel the same 965.6 km (600 miles)in just over 47 minutes. a. 47 min = s b. What is its speed in meters per second? G U E S S 4. The fastest train on Earth, the Japanese Shinkansen, can travel at faster speeds than trains in the United States. During a speed test, the train traveled 631.7 km (392.5 miles) in 2.5 hours. a. 631.7 km = m b. 2.5 hours = s c. What is the train’s average speed? G U E S S 5. The World Water Speed record, like the air speed record, is decades old. Australian Ken Warby set the record in 1978 when he averaged 142 meters per second (317.60 mph) in a 27-foot jet-powered hydroplane called Spirit of Australia. During a practice run the hydroplane travels 402.3 km (250 miles). a. 402.3 km = m b. How long does it take to travel 402.3 km (250 miles)? G U E S S 6. The fastest plane ever made, the Lockhead SR71, was able to travel 983.5 meters per second (2200 miles per hour). Based on this speed, showing GUESS for each how far could it travel in: a. 2 hours? G U E S S b. 3 hours? G U E S S c. 5 hours? G U E S S 7. During liftoff, the Discovery space shuttle can exceed 8 kilometers per second (>Mach 24). If the shuttle were to travel at this speed for 10 minutes, how far in meters has it traveled? (Hint: convert all your values to the same base units!) G U E S S .
