Question

Given that the moon is 384400 km away from us (take this to be the distance from the center of the Earth to the center of the Moon) and that the radius of the Earth is 6371 km, calculate the differenc

Answer 1

Sure! We want to find out how far the Moon is from the surface of the Earth.

We're given two distances:

1. The distance from the center of the Earth to the center of the Moon. We know that this is 384400 kilometers.
2. The radius of the Earth, which is 6371 kilometers. This is the distance from the center of the Earth to its surface.

To get the distance from the surface of the Earth to the Moon, we need to subtract the Earth's radius from the total distance to the Moon's center.

So, let's start with the total distance from the Earth's center to the Moon's center:

384400 kilometers.

Then we'll subtract the Earth's radius:

384400 kilometers - 6371 kilometers.

This equals to 378029 kilometers.

So, the distance from the surface of the Earth to the Moon is 378029 kilometers. This is the result after performing the calculations.
