Question 634468
Okay, let's dissect this into an equation.
<p>Two planes which are 2475 miles apart fly towards each other. {{{x+y=2475}}}
<p>Their speeds differ by 75 mph. {{{x+75+x=2475}}}
<p>If they pass each other in 3 hours, what is the speed of each. {{{(x+75+x)/3=2475}}}
<p>Now, we just simplify using PEMDAS.
<p>{{{(2x+75)/3=2475}}}
<p>{{{2x+75=825}}}
<p>{{{2x=750}}}
<p>{{{x=375}}}
<p>Now, we just add 75mph to one of the planes, making <b>one plane go at 450mph and the other at 375mph.</b>
<p>Hope this helps!
