Solve the following problems. Show your work on another sheet of paper.
A plane that travels at Mach 1 is traveling at the speed of sound. Mach 2 is twice the speed of sound, Mach 3 is three times the speed of sound, and so on. (The speed of a jumbo passenger jet is less than Mach 1.)
Mach Speeds * | |
---|---|
Mach 1 | 680 mph |
Mach 2 | 1,360 mph |
Mach 3 | |
Mach 4 | |
Mach 5 |
1 Complete the table by finding the missing speeds in miles per hour (mph).
2 A plane traveling at Mach 5 travels a little faster than how many miles per minute?
3 The X-43, an unmanned scramjet plane, can reach a speed of nearly Mach 10.
a. Find the speed in miles per hour of the X-43.
b. The X-43 travels a little faster than how many miles per minute?
