Question

Which of the following corresponds to a supersonic speed?

a. Mach0.5b) Mach 1.0
c. Mach 1.5

Answer 1

The answer is MACH 1.5

Step-by-step explanation:

Supersonic speed is anywhere from 1.5 Mach to 5 Mach.

Answer 2

Answer=C

Supersonic speed is a rate of travel that exceeds the speed of sound. The speed of sound is Mach 1

a. Mach 0.5

b. Mach 1

c. Mach 1.5

C is the correct answer. Mach1.5>Mach1

a is less than the speed of sound, therefore it doesn't exceed it.
Mach0.5<Mach1

b is exactly the speed of sound, so it doesn't exceed it.
Mach1=Mach1
