Algebra.Com's Answer #473934 by FrankM(1040)![]() ![]() You can put this solution on YOUR website! In an hour, the slower car moves 40 miles. At that point the second car is approaching it at a rate of 20MPH, the difference of their two speeds. It takes two hours to catch up. \n" ); document.write( " |
