part a: distance conversions
1.
earth's diameter is 12,756 kilometers. how many meters is this?
2.
the diameter of earth's moon is 3,476 kilometers. express this distance in kilometers?
3.
the average distance between earth and it’s moon is 384.000.000 meters. express this distance in kilometers?
4.
a billion years ago, earth and its moon were just 200,000 kilome

1.

Earth's diameter is 12,756 kilometers. How many meters is this? 12756000

2.

The diameter of Earth's moon is 3,476 kilometers. Express this distance in kilometers?  347 600 000 centimetres, I think its supposed to say centimeters

3.

The average distance between Earth and it’s moon is 384.000.000 meters. Express this distance in kilometers? 384000

4.

A billion years ago, Earth and its moon were just 200,000 kilometers. I dont know how to answer this.
