all this is asking is what is 5 times 5. the answer is 25.
A speed that is more than five times faster than the speed of sound is equivalent to Mach 5. In this case, the speed range you provided, 3820-7640 mph, falls within the Mach 5 category.
True. Check page 397.
"Hypersonic" is a slippery, rubber, inexact word meaning faster than around five times the speed of sound in the same medium, or, you might say, 'super supersonic'. If you define it, for a moment, as "exactly 5 times the speed of sound at sea level", then the speed of light is only 174,806 times that fast. Nothing is faster than the speed of light.
Mach 5, 5 times faster than the speed of sound!
Running speed is about 3 m/s Light speed is about 300000000 m/s That's 10^8 times faster
speed of cellonics modem is 1000 times faster than normal modems
Broadband is faster than any dial up connection usally by at least 10-30 times faster speed.
No real limit, up to the speed of light. The Apollo astronauts traveled at ABOUT 32 times the speed of sound on their trip to the moon. That is the fastest yet.
When sound waves go through liquids, they travel five times as faster than they do on land. When sound waves go through solids though, they don't go as fast.
Roughly speaking, light moves about a million times faster than sound in air.
The type of aircraft that flies faster than the speed of the sound are called SuperSonic aircraft.There are many supersonic aircrafts. Nowadays there are also HyperSonicaircrafts. The maximum speed recorded is Mach 9.6 (9.6 times faster than the speed of sound) by X-43A.
Travelling faster than the speed of light is not possible, therefore no galaxies have travelled or are travelling faster than the speed of light.
