Question

A billion years ago, Earth and its moon were just 200000 kilometers apart. Express this distance in meters.​

Answer 1

Answer:

The  value is  $x = 200000000 \ m$

Explanation:

From the question we are told that

  The  distance between the earth and the moon is  $d = 200000 \ km$

Generally ,

     $1 \ km = 1000 \ m$

      $200000 \ km \to x \ m$

=>    $x = \frac{200000 * 1000}{1 }$

=>   $x = 200000000 \ m$
