Algebra.Com's Answer #282830 by ankor@dixie-net.com(22740)![]() ![]() You can put this solution on YOUR website! a car traveled at a steady speed for 130 km. due to a mechanical problem, it returned at half that speed. \n" ); document.write( "if the total time for the round trip was 4 hours 30 minutes, find the two speeds? \n" ); document.write( ": \n" ); document.write( "Let s = the slower speed \n" ); document.write( "then \n" ); document.write( "2s = the faster speed \n" ); document.write( "; \n" ); document.write( "Write a time equation, time = dist/speed \n" ); document.write( " \n" ); document.write( "find s, by multiplying by 2s, results: \n" ); document.write( "130 + 2(130) = 4.5(2s) \n" ); document.write( "you should be able to solve it now \n" ); document.write( " \n" ); document.write( " |
