Algebra.Com's Answer #551580 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! A plane can fly 720 miles in the same time as it takes a car to go 200 miles. If the car travels 130 mph slower than the plane, find the speed of the plane. \n" ); document.write( "------- \n" ); document.write( "Plane rate = 720/t mph \n" ); document.write( "Car rate = 200/t mph \n" ); document.write( "------ \n" ); document.write( "Equation:: \n" ); document.write( "plane rate - car rate = 120 mph \n" ); document.write( "------ \n" ); document.write( "720/t - 200/t = 120 mph \n" ); document.write( "---- \n" ); document.write( "720 - 200 = 120t \n" ); document.write( "--- \n" ); document.write( "120t = 500 \n" ); document.write( "t = 4.16666... \n" ); document.write( "--------------- \n" ); document.write( "Ans: plane speed = 720/4.16666 = 172.8 mph \n" ); document.write( "--------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "------------- \n" ); document.write( " |
