Let x = the speed rate of the helicopter in mph
\n" ); document.write( "x + 360 = the speed rate of the jet in mph\r
\n" ); document.write( "\n" ); document.write( "Travel time is calculated as distance traveled divided by speed rate\r
\n" ); document.write( "\n" ); document.write( "810/(x+30) = time traveled by jet\r
\n" ); document.write( "\n" ); document.write( "162/x = time traveled by helicopter\r
\n" ); document.write( "\n" ); document.write( "So we have the following equation:\r
\n" ); document.write( "\n" ); document.write( "810/(x+360) = 162/x
\n" ); document.write( "Solve for x
\n" ); document.write( "810(x) = 162(x+360)
\n" ); document.write( "810x = 162x + 58,320
\n" ); document.write( "810x - 162x = 58,320\r
\n" ); document.write( "\n" ); document.write( "648x = 58,320
\n" ); document.write( "x = 58,320/648
\n" ); document.write( "x = 90
\n" ); document.write( "x + 360 = 450 (speed of the jet\r
\n" ); document.write( "\n" ); document.write( "Answer:
\n" ); document.write( "The speed rate of the jet is 450 mph.\r
\n" ); document.write( "\n" ); document.write( "Solved.\r
