A jet aircraft is traveling at Mach 2.5 through air at 1 °C. What is the jet's speed in m/sec?
I can do the equation myself, I just need to know what equation I need to do in order to find the answer.

mach=speed sound
what is the speed of sound at 1C?
vsound=If I remember correctly 331(1+.6TempinC)
check that formula.
get the speed of sound, multiply it by 2.5
