\n" );
document.write( "Note: D = r*t  OR t = D/r
\n" );
document.write( "Let s represent how fast can the plane travel with no wind resistance
\n" );
document.write( " 910/(s+35mph) = 760/(s - 40mph) |Cross multiply to solve for s
\n" );
document.write( " 910(s-40) =  760(s+35)
\n" );
document.write( "   150s = 63000
\n" );
document.write( "      s = 420mph \n" );
