Question

Express the distance between the moon and earth in meters with a meter prefix (km).

Answer 1

`0.384 Gm`

Step-by-step explanation:

The average distance between the moon and earth is 384,400 km

Why average distance? Well, the Moon is not always the same distance from Earth, its orbit is not a perfect circle.

Expressing this distance in meters we have:

`384000km*(1000m)/(1km)=0.384*10^9m`

Since 1 gigameter (Gm) is
`10^9 m`:

`0.384*10^9m=0.384 Gm`

Answer 2

Answer;

= 3.86 × 10^8 Meters

Explanation;

-The distance between the Earth and the moon is 386000 km

But; 1 km = 1000 m

Therefore; 386000 km will be equivalent to;

= 386000 × 1000

= 386000000 m

= 3.86 × 10^8 meters
