(The actual distance between the Earth and the Sun is 1.5 × 108 km.) Note: your answer should be entered in meters (m) . Round your answer to the nearest meter

Answer 1

Hi Sannaa,

 

You want the distance in meters you are given the scale 

200mm: 384400km,  where 1meter =1000mm, because you 

   1 mm:1922 km

 

1.5x10⁸ km = 1.5x10⁸ km*1 mm/1922 km=78044 mm*1 meter/1000mm

                  = 78 meters
