Algebra.Com's Answer #353324 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! At 10:00 am, a car leaves a home at a rate of 60 mi/h. At the same time, another care leaves the same home at a rate of 50 mi/h in the opposite direction. \n" ); document.write( " At what time will the cars be 330 miles apart? \n" ); document.write( ": \n" ); document.write( "You can do this in your head, the relative speed of the two cars is the sum which is 110 mph, divide that into 330 and get 3 hrs, 1 PM is answer \n" ); document.write( ": \n" ); document.write( "However, they may want you to show some equations here \n" ); document.write( ": \n" ); document.write( "Let t = time for this to be true; \n" ); document.write( "write a distance equation, dist = speed * time \n" ); document.write( "60t + 50t = 330 \n" ); document.write( "solve for t \n" ); document.write( " |
