Objest Velocity

Question

If an object has a constant velocity of mach 5.0, how many seconds (X Sec) would it take to travel 225 feet?

Answer 1

You have a Mach number of 5.0, which is not a velocity, but a ratio of velocity to the local speed of sound.  To answer your question, you need to also know what the local speed of sound is.  Then multiply the local speed of sound by the Mach number to get velocity, and divide the distance by the velocity to get travel time.
