The space shuttle is a fast-moving machine. When it's in orbit, the Mission Control Center at the Johnson Space Center in Houston, Texas, keeps track of the shuttle's motion. The first shuttle
mission in 1981 traveled more than I million km during a flight lasting more than 54 h. That's an average speed of almost 32,000 km/h. Investigate space shuttle data to find how far the shuttle
has flown on each mission as well as the amount of time each mission lasted. With that data, you'll be able to calculate the average speed at which the space shuttle flies.
