Algebra.Com's Answer #42362 by asha(30)![]() ![]() ![]() You can put this solution on YOUR website! let the distance from Portland to El Paso be x miles \n" ); document.write( "the speed of the plane is 303 m.p.h \n" ); document.write( "the speed of the car is 50 m.p.h. \n" ); document.write( "time taken by the plane to fly the distance is x/303 hrs. \n" ); document.write( "time taken bythe car to travel the same distance is x/50 hrs. \n" ); document.write( "but it is given that \n" ); document.write( "x/50 -x/303 =35.42 \n" ); document.write( "x(1/50-1/303) =35.42 \n" ); document.write( "x(303-50)303*50=35.42 \n" ); document.write( "253*x =35.42*303*50 \n" ); document.write( "x=( 35.42*303*50)/253 \n" ); document.write( " = 2121 miles \n" ); document.write( "you can check the answer by plugging in the values in the equation. \n" ); document.write( "good luck !!! \n" ); document.write( " |
