Question 898324

airplane A and airplane B fly along parallel paths each 3000 miles long. A flies at a constant speed of 600 miles per hour and B flies at a constant speed of 580 miles per hour. If they start at the same time, how many more miles are left for B to fly after A completes its flight?
<pre>
Plane A completed 3,000-mile trip in {{{3000/600}}}, or 5 hours
In 5 hours, Plane B completed 580(5), or 2,900 miles
Therefore, after Plane A had completed its flight, Plane B still had {{{highlight_green(100)}}} (3,000 - 2,900) miles to go.
