Algebra.Com's Answer #441365 by graphmatics(170)![]() ![]() You can put this solution on YOUR website! Let t be the time in hours that the 2 cars travel. Then at the time the cars are 76 miles apart the cars will have traveled 46*t and 30*t. If they are 76 miles apart then \n" ); document.write( "46t-30t=76 \n" ); document.write( "So \n" ); document.write( "16*t=76 \n" ); document.write( "t=76/16 \n" ); document.write( "t=4.75 \n" ); document.write( "So it takes 4.75 hours for the cars to be 76 miles apart. .75% of an hour is 45 minutes, so the time they will be 76 miles apart is 6:45. \n" ); document.write( " |
