Answer:
The plane travels at a rate of 313 meters per second.
Explanation:
Since the speed of sound at an elevation of 40,000 feet, where many aircraft fly, is 295 m / s, if an airplane is flying at Mach 0.92 at this altitude, to determine how fast is the airplane traveling in meters per second you must perform the following calculation:
1 Mach = 1,225.04 km / h
1 km = 1,000 m
1 h = 3,600 sec
1 = 1225.04
0.92 = X
0.92 x 1225.04 = X
1,127.03 = X
(1,127.03 x 1,000) / 3,600 = X
1,127,030 / 3,600 = X
313.06 = X
Thus, the plane travels at a rate of 313 meters per second.
