document.write( "Question 1093353: two planes leave from Atlanta Georgia. one makes a 5.5 hr flight to Seattle, Washington and the other makes a 2 hr flight to Boston, Massachusetts. The plane to Boston averages 28 mph slower than the plane to Seattle. If the total distance traveled by both planes is 3124 mi, determine the average speed of each plane \n" ); document.write( "

You can put this solution on YOUR website!
Let the speed of Seattle plane = $\"+s+\"$ mi/hr
\n" ); document.write( " $\"+s+-+28+\"$ = speed of Boston flight
\n" ); document.write( "Let $\"+d+\"$ = distance in miles to Seattle
\n" ); document.write( " $\"+3124+-+d+\"$ = distance to Boston
\n" ); document.write( "----------------------------------------
\n" ); document.write( "(1) $\"+d+=+s%2A5.5+\"$
\n" ); document.write( "(2) $\"+3124+-+d+=+%28+s+-+28+%29%2A2+\"$
\n" ); document.write( "-------------------------------------
\n" ); document.write( "Solve for $\"+s+\"$ and $\"+s-28+\"$ , then check answer by plugging
\n" ); document.write( " $\"+s+\"$ back in and solving for $\"+d+\"$
\n" ); document.write( " \n" ); document.write( "
