1680 miles/3hours=560 mph The combined speed of the two planes is 560 mph.
\n" ); document.write( "r=speed of slower plane; r+60mph=speed of faster plane
\n" ); document.write( "r+r+60mph=560mph
\n" ); document.write( "2r=500mph
\n" ); document.write( "r-250mph ANSWER 1: The speed of the slower plane is 250mph.
\n" ); document.write( "r+60mph=250mph+60mph=310mph ANSWER 2: The speed of the faster plane is 310 mph.\r
