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( "\"130%2F%282s%29\" + \"130%2Fs\" = 4.5
\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( "
