How long will it take us to reach the moon in the speed of light?

Answer 1

The Moon averages 386,243km (240,000 miles) away from Earth. In theory that distance could be traveled in 3862 hours (161 days) at 100kph. In practical terms, you'd never get there from Earth. To escape Earth's gravity, a spacecraft needs to travel faster than 11.25 km (7 mi) per second. A speed of 100kph is only a fraction of that (about .027kps), so it wouldn't work. The Apollo Moon missions left the ground and accelerated to about 28000kph, until they entered a "parking orbit" of about 183.465km (114 miles) above the Earth's surface. They then left Earth orbit at about 39000kph. (The spacecraft decelerated on its own, during the trip.)

Answer 2

Since the moon's orbit is elliptical (oval-shaped), its distance varies from about 221,463 miles (356,334 kilometers) at perigee (closest approach to Earth) to 251,968 miles (405,503 kilometers) at apogee (farthest point). The average distance from the moon to the Earth is 238,857 miles (384,392 kilometers).

So do to the elliptical orbit we will us the average distance of 238,857 miles for these answers.

So if you are going 100MPH it will take a little more then 99 days.

It is also said that the speed of light is 186,000 MILES PER SECOND, so at that speed going to the moon it would take
