About Miles per Minute

A mile per minute (mi/min) = exactly 26.8224 m/s = 60 mph. The X-15 rocket plane flew at ~4.5 mi/min (Mach 6.7); the SR-71 Blackbird at ~2.1 mi/min (Mach 3.2). Speed of sound at sea level ≈ 0.77 mi/min. 'Mile-a-minute' (60 mph = 1 mi/min) was a historic railway milestone first achieved on the Great Western Railway in the 1840s. 1 mi/min = 96.5604 km/h.

About Orbital Speed (ISS)

The ISS orbits at ~408 km altitude at ≈7,660 m/s (27,576 km/h) - the practical LEO benchmark. At this speed it completes one orbit in 92.68 min (15.5 orbits per day), giving astronauts 16 sunrises and sunsets every 24 hours. Delta-v to reach LEO from Earth's surface is ~9,400 m/s (with gravity and drag losses). GEO at 35,786 km requires only ~3,075 m/s per Kepler's third law. 1 ISS speed ≈ 7,660 m/s.
