Algebra.Com's Answer #25369 by stanbon(75887) ![]() You can put this solution on YOUR website! An airplane flew for 6 hrs against a tail wind of 25km/hr. The return trip with the samewind took 5 hrs. Find the speed of the plane still in the air.\r \n" ); document.write( "\n" ); document.write( "Downwind Data: \n" ); document.write( "Time =5 hrs.; Rate=Plane speed(p) + 25km/hr. \n" ); document.write( "Upwind Data: \n" ); document.write( "Time=6 hrs.: Rate=Plane speed(p) - 25km/hr. \n" ); document.write( "EQUATION: \n" ); document.write( "Distance Downwind = Distance Upwind \n" ); document.write( "5(p+25)=6(p-25) \n" ); document.write( "5p+125=6p-150 \n" ); document.write( "p=275 km/hr \n" ); document.write( "Plane speed in still air = 275km/hr. \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " \n" ); document.write( " |
