Algebra.Com's Answer #46202 by Nate(3500)![]() ![]() ![]() You can put this solution on YOUR website! If the plane keeps its own constant rate: \n" ); document.write( "Rate against wind = planespeed - windspeed = 720 \n" ); document.write( "planespeed - 30 = 720 \n" ); document.write( "planespeed = 750mi \n" ); document.write( " |
