twice as much as 1 child
Mach 2.
The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.
Mach 2 = 1,322.94 knots
No Mach 2.3
If it is civil , its mach 1.- mach 2 ,name is Concorde & in defence they go beyond mach 2
There is no plural for the noun 'mach'; the different levels of mach are usually shown by a numeral for various speeds, such as mach 1 or mach 2.
mach 1 = the speed of sound mach 2 is twice the speed of sound and that's how fast Concorde could travel, well, mach 2.3
Frantisek Mach is 6' 1 1/2".

Mach refers to the speed of sound, for example, mach 1, equals the speed of sound, mach 2, the speed of sound times 2. So, mach 25 would mean, 25 times the speed of sound.
Typically, a child can carry around 20-30 pounds, and a horse can carry around 20-25% of its body weight. Assuming the children weigh around 70 pounds each, and the horse weighs 1000 pounds, they could carry a total of 2030-2120 pounds, which is around 1-1.5 tons of coal.

For an Exotic read "The AURORA Program" sees the stealth aircraft evidence supporting Mach 8 and beyond. It would depend on the jet itself. Each jet has a different engine (thrust production), weight, lift and drag component which all effect the top speed of fighter jets. For example the f18 hornet has a top speed of mach 1.8 (1190 kph) whilst the yet the mig 35 can get to mach 2.25(2400 kph)
