The speed of sound in air is approximately 343 meters per second. To convert this to kilometers per minute, we need to multiply by 60 seconds (1 minute). Therefore, the sound would travel 20,580 meters in 1 minute, which is equivalent to 20.58 kilometers.

Depends on the quality of air and any obstacles. Under perfect conditions (dry, clean, 20 degree Celsius air), sound would travel 20.6 kilometers per minute.
As we know that 1 hour consists of 60 minutesso, 1 minute would be of 1/60 hours (or 0.0166666666666667 hours approximately)Thus, 0.7 kilometers/minute can be written as0.7 kilometers/0.0166666666666667 hourswhich, on simplification (calculation) gives 42 kilometers per hour.Result42 kilometers per hour
24.14 km per hour for a 4-minute mile.
about 6 hours and 40 minutes
In order to calculate how many minutes it would take someone to travel 5 kilometers you need to know the speed the person is traveling at. For example if the person is traveling at a speed of 60 kilometers an hour it would take them 5 minutes to travel 5 kilometers.
Mach velocities are all relative to the speed of sound in that gas, at that density. Mach 1 = the speed of sound. Mach 2 = twice the speed of sound. It does not have an invariant conversion into miles per minute.
