Mach 0.87 is approximately 87% of the speed of sound in air. At sea level and at standard atmospheric conditions, the speed of sound is about 343 meters per second (1,125 feet per second), so Mach 0.87 would be around 299 meters per second (980 feet per second). This speed is commonly encountered in high-performance aircraft and is significantly faster than typical commercial jet speeds.
