How fast is 1.6 mock?

A mock speed of 1.6 refers to a speed that is 1.6 times the speed of sound, known as Mach 1. At sea level, where the speed of sound is approximately 343 meters per second (1,125 feet per second), Mach 1.6 would be around 549 meters per second (1,804 feet per second). This speed is typically associated with high-performance aircraft and supersonic travel.
