Algebra.Com's Answer #622322 by fractalier(6550)![]() ![]() You can put this solution on YOUR website! Call the time he traveled at 40 mph, t. \n" ); document.write( "Then the time he traveled at 35 mph would be 7-t. \n" ); document.write( "We then write \n" ); document.write( "40t + 35(7-t) = 265 \n" ); document.write( "40t + 245 - 35t = 265 \n" ); document.write( "5t + 245 = 265 \n" ); document.write( "5t = 20 \n" ); document.write( "t = 4 hours at 40 mph \n" ); document.write( "7-t = 3 hours at 35 mph \n" ); document.write( " |
