This is an RTD problem. WE can create a table based on the given information:
\n" ); document.write( "PLANE . . . . . .rate . . . . . . . .time . . . . . . . distance
\n" ); document.write( "against . . . . . .r-c . . . . . . . .6 . . . . . . . . . . .900
\n" ); document.write( "with . . . . . . .. r+c . . . . . . .. 5 . . . . . . .. . . . .900
\n" ); document.write( "RT=D
\n" ); document.write( "or r = D/T
\n" ); document.write( "r-c = 150
\n" ); document.write( "r+c = 180
\n" ); document.write( "adding down we get
\n" ); document.write( " 2r = 330
\n" ); document.write( "r = 165
\n" ); document.write( "rate with no wind is 165 mph
\n" ); document.write( "c = 15 mph
\n" ); document.write( "
\n" );
