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
