Question 211000
According to the directions in the problem, the scale is {{{10^8}}}miles per cm.
To find the number of centimeters on the chart that corresponds the the number of miles of each of the astronomical bodies, one must divide the given number of miles in each case by {{{10^8}}}miles per centimeter.
For example, in the case of Saturn at {{{10^9}}}miles from earth:
{{{10^9/10^8 = highlight(10)}}}cm. on the chart.
Andromeda galaxy at {{{10^19}}}miles from earth:
{{{10^19/10^8 = highlight(10^11)}}}cm. on the chart.
Quasar OQ172 at {{{10^22}}}miles from earth:
{{{10^22/10^8 = highlight(10^14)}}}cm. on the chart.
