Answer:♀️
Step-by-step explanation:
the question is confusing but the ? angle is 90 degrees don't know if that helps at all though sorry
We can set up a proportion since we know the ratio between the # of purple marbles and the # of green marbles.
A ratio is a way to compare two different values: for every 8 purple marbles there are 5 green marbles
<h2>

</h2><h2 /><h2>when we cross multiply, we get 5p = 240 </h2><h2>we divide both sides by 5 to isolate the variable </h2><h2 /><h3><u>There are 48 purple marbles </u></h3>
470 miles in 2 hrs......470/2 = 235 per hr
in 12 hrs...
235 * 12 = 2820 miles <==
