Okay, let's dissect this into an equation.
\n" ); document.write( "

Two planes which are 2475 miles apart fly towards each other. $\"x%2By=2475\"$
\n" ); document.write( "

Their speeds differ by 75 mph. $\"x%2B75%2Bx=2475\"$
\n" ); document.write( "

If they pass each other in 3 hours, what is the speed of each. $\"%28x%2B75%2Bx%29%2F3=2475\"$
\n" ); document.write( "

Now, we just simplify using PEMDAS.
\n" ); document.write( "

$\"%282x%2B75%29%2F3=2475\"$
\n" ); document.write( "

$\"2x%2B75=825\"$
\n" ); document.write( "

$\"2x=750\"$
\n" ); document.write( "

$\"x=375\"$
\n" ); document.write( "

Now, we just add 75mph to one of the planes, making one plane go at 450mph and the other at 375mph.
\n" ); document.write( "

Hope this helps! \n" ); document.write( "
