They do have the same average speed ... it's called the air temprature.
I believe you need to define average for yourself.
Temperature is a measure of the average kinetic energy of the particles in a substance. It indicates how hot or cold an object is by quantifying the energy of its molecules. Temperature is typically measured using the Celsius (°C) or Fahrenheit (°F) scale.
The boiling point of iodine (184.3 0C) is substantially higher than the boiling point of chlorine (-34 0C). Each element occurs at standard temperature and pressure as diatomic molecules; iodine molecules have substantially more mass than chlorine molecules; dispersion forces will be higher beween iodine molecules as they have more electrons than chlorine molecules. Both these factors contribute, mass will alomost certainly be the predominant factor.
If the star is moving in the same direction and at the same speed as Earth, there would be no Doppler shift in the spectrum observed from Earth. The star's light would not be blueshifted or redshifted relative to Earth, since the relative motion is negligible.
Temperature is the measure of the average kinetic energy of the molecules involved. If the temperature increases, then the kinetic energy of the molecules increases and they move faster. Faster moving molecules have more collisions with other molecules and more forcefully. For a reaction to occur, the molecules have to line up correctly and with adequate force. By increasing the speed of the particles, you are increasing the chance that the two molecules will align and produce a reaction.
Bert's actual speed would be 46mph, as you would add the speed of the tailwind to his traveling speed.
The instantaneous speed of water molecules in a bucket of water would vary due to the random motion and collisions between molecules. On average, the speed of water molecules at room temperature is around 500 m/s.
The speed of gas molecules is primarily determined by their temperature, not their specific identity. At the same temperature, bromine molecules and air molecules would have similar average speeds.
I would call it current speed, not average speed.
If the temperature of a gas is doubled, the mean speed of the gas molecules will also double. This is because the average kinetic energy of the gas molecules is directly proportional to the temperature according to the kinetic theory of gases.
The light molecules would have greater speed because they have lower mass and therefore higher speed for the same kinetic energy. This is described by the relationship between kinetic energy, mass, and speed in the equation KE = 1/2 mv^2, where kinetic energy (KE) is proportional to the mass (m) and the square of the velocity (v).
ionic molecules dissolve the most. but some polar covalent molecules also do dissolve in water.
In Earth's atmosphere, you would expect to find gases like oxygen (O2), nitrogen (N2), and hydrogen (H2) as molecules, which are composed of two or more atoms bonded together. Gases such as helium (He), neon (Ne), and argon (Ar) are present as individual atoms since they are noble gases that exist as single atoms and do not typically form molecules in the atmosphere.
At an average 50 mph, 60 hours. At an average 60 mph, 50 hours.

Warmer Air does this.
The air molecules would go very slow because the air molecules are tight close together.
The general tendency is for the average speed of particles to increase as temperature increases.But please note that temperature can't be DEFINED simply as the average speed; it is more closely related to the average ENERGY per particle. And the energy for each particle depends on the SQUARE of the speed; but it also depends on the mass of the particle.
