Algebra.Com's Answer #837001 by Theo(13342)![]() ![]() You can put this solution on YOUR website! r * t = d \n" ); document.write( "r is the rate \n" ); document.write( "t is the time \n" ); document.write( "d is the distance. \n" ); document.write( "for homer: \n" ); document.write( "17 * 20 = d + 60 \n" ); document.write( "for mae: \n" ); document.write( "r * 20 = d \n" ); document.write( "solve for d in homer equation to get d = 17 * 20 - 60 = 280. \n" ); document.write( "solve for r in mae equation to get r * 20 = 280 resulting in r = 14. \n" ); document.write( "mae was driving at 14 miles per hour should be your solution. \n" ); document.write( "confirm by replacing r with 14 in mae's equation and by replacing d with 280 in both equations to get: \n" ); document.write( "17 * 20 = 280 + 60 resulting in 340 = 340 in homer equation. \n" ); document.write( "14 * 20 = 280 resulting in 280 = 280 in mae eqution. \n" ); document.write( "homer drove 340 miles in 20 hours. \n" ); document.write( "mae drive 280 miles in 20 hours. \n" ); document.write( "homer drove 60 more miles than mae in the same time. \n" ); document.write( "solution is mae drove at 14 miles per hour.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
