The average distance between Earth and Moon is approximately 30 times Earth's diameter.
If you could fly to the Moon at a constant speed of 1000 kilometers per hour, which is the speed of a fast passenger jet, it would take sixteen days to get there. Apollo astronauts reached the Moon in less than four days even though they coasted "uphill" almost the entire distance. They got a fast start.
The Sun happens to be 400 times the Moon's diameter, and 400 times as far away. That coincidence means the Sun and Moon appear to be the same size when viewed from Earth. A total solar eclipse, in which the Moon is between the Earth and Sun, blocks the bright light from the Sun's photosphere, allowing us to see the faint glow from the corona, the Sun's outer atmosphere.
When the Moon is at apogee, it is 11% farther from Earth than it is at perigee. This is far enough that it cannot entirely block the bright light, so eclipses which occur near apogee are not total.
Perigee 363,300 km
Mean 384,400 km
Apogee 405,500 km

In astronomy, a lunar distance ( LD ) is a measurement of the distance from the Earth to the Moon. The average distance from Earth to the Moon is 384,403 kilometers (238,857 miles).
High-precision measurements of the lunar distance are made by measuring the time taken for light to travel between LIDAR stations on Earth and retroreflectors placed on the Moon.
The moon is spiraling away from Earth at an average rate of 3.8 cm per year, as detected by the Lunar Laser Ranging Experiment.
The first person to measure the distance to the moon was Hipparchus, who used simple trigonometry. He was approximately 26,000 km off the actual distance-an error of about 6.8%. Hipparchus was alive during 2nd Century BC.

The average distance between the Earth and Moon is approxamately 30 times Earth's diameter.

A good "rule of thumb" value to remember is a quarter million miles. More
precisely, the Moon's orbit is elliptical: its average orbital radius is
384401 km, apogee (farthest distance from the Earth) is 406700 km, and
perigee (distance of closest approach to the Earth) is 356400 km.

The distance is nearby 384,400 km. and nearby.
Because moon has not same distance ever.it comes near the earth or goes far from the earth.

The mean distance to the Moon from the Earth is 3.8 x 105 km or 2.4 x 105 miles. Closest (perigee) 3.5 x 105 km. Furthest (apogee) 4.1 x 105 km.

"the average distance between Earth and Moon is approximately 30 times the Earth's diameter". and the earths diameter is about 12,756.3 KM. you do the math.

It varies. The moon is actually in an eliptical orbit:
Closest: Perigee 363,300 km
Average: Mean 384,400 km
Farthest: Apogee 405,500 km
