About Mach 1

Mach 1 = the speed of sound in dry air at ISA sea-level (15°C, 101.325 kPa) = exactly 340.29 m/s (1,225 km/h; 761 mph). Chuck Yeager first exceeded it on 14 October 1947 in the Bell X-1. At 35,000 ft cruise altitude (−56.5°C), it falls to 295.1 m/s. Flight regimes: subsonic Mach 5. Concorde cruised at Mach 2.02; SR-71 at Mach 3.2. 1 Mach 1 = 340.29 m/s.

About Yards per Second

A yard per second (yd/s) = exactly 0.9144 m/s - brisk jog speed, natural for American and British sports. American football wide receivers at full sprint: 10-11 yd/s; defensive backs 9-10 yd/s. Ten-pin bowling ball rolls the 20 yd lane in 2-3 s ≈ 7-9 yd/s. A sprinting cricket fielder covers the 22 yd pitch in ~3 s ≈ 7 yd/s. Racing greyhound: ~20 yd/s. 1 yd/s = 0.9144 m/s = 2.04545 mph.
