Oh, dude, going around the world at Mach 5? That's like super speedy, man! Well, technically, if you were able to maintain that speed consistently without any obstacles or refueling stops, it would take you around 8.5 hours to circumnavigate the globe at Mach 5. Just a casual jaunt around the planet, no big deal.
About 37 hours 20 minutes.
Traveling around the world at Mach 2, which is approximately 1,535 miles per hour (2,469 kilometers per hour), would take about 12 hours. The Earth's circumference is roughly 24,901 miles (40,075 kilometers), so dividing this distance by the speed gives the estimated travel time. However, this is a theoretical calculation and does not account for factors like flight paths, refueling, or air traffic regulations.
The cruising speed of the Concorde was mach 2.04, or about 1552 miles per hour. Assuming that you are referring to a non-stop flight around the equator, it would take a Concorde about 16 hours to fly around the world at that speed, ignoring weather, actual range, and the rotation of the Earth.
Mach 3.5 is about 2,595.4 mph
8000 mph is approximately Mach 10.5 under standard conditions.
The speed of sound is around 760 miles per hour = Mach 1. So Mach 4 is 4*760 = 3040 mph.
60 minutes (4x15minute quarters)
The SR71 blackbird flies at around 3535 km per hour which is close to mach 3 (3 times the speed of sound). The peed of sound is 1193.04 km per hour. The circumfrence of the earth along the equator is about 40,075.16 km. Divide the distance of the earth and mach 3 and you should get an answer of around 11 hours and 30 min. Note that it may vary in the real world due to temperature, altitude, gas breaks, etc.
It depends on how fast they are flying. At mach 1 it would take an hour and a half.
Mach 6 is six times the speed of sound, which is approximately 2,300 meters per second (or 5,100 miles per hour). At Mach 6, an object would be traveling at around 6,917 meters per second (or 15,459 miles per hour).
60 minutes (4x15minute quarters)
0.96 mach is 96% the speed of sound. Mach 96 would be 96 times the speed of sound.
