altitude A=3048+60.5x, where x is in seconds.
\n" ); document.write( "altitude B=4500+30.25x
\n" ); document.write( "set them equal
\n" ); document.write( "3048+60.5x=4500+30.25x
\n" ); document.write( "30.25x=1452
\n" ); document.write( "x=48 seconds
\n" ); document.write( "the altitude will be 4500+30.25*48=5952 feet
\n" ); document.write( "
