\n" ); document.write( "if it takes Plane B the same amount of time to travel 1710 miles.
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "Let \"u\" be the speed of the plane A, in mph.\r\n" );
document.write( "\r\n" );
document.write( "Then the speed of the plane B is (u+95) mph, according to the condition.\r\n" );
document.write( "\r\n" );
document.write( "Flight time for plane A is  hours  ( remember, speed = distance/time ! )\r\n" );
document.write( "\r\n" );
document.write( "Flight time for plane B is .\r\n" );
document.write( "\r\n" );
document.write( "The condition says these times are the same (!). It gives you an equation\r\n" );
document.write( "\r\n" );
document.write( " = .\r\n" );
document.write( "\r\n" );
document.write( "You need to solve it for u.\r\n" );
document.write( "\r\n" );
document.write( "To make it, multiply both sides by u*(u+95). You will get\r\n" );
document.write( "\r\n" );
document.write( "1425(u+95) = 1710u.\r\n" );
document.write( "\r\n" );
