Part 1:
\n" ); document.write( "Let the time be measured as 't'.
\n" ); document.write( "The distance traveled when the woman meets the cyclist will be the same (d=d). The time for the cyclist, however, will be three hours lass than the time for the woman.
\n" ); document.write( "Distance = Rate * Time
\n" ); document.write( "For the woman, d = 3 * t.
\n" ); document.write( "For the cyclist, d = 12 * (t - 3).
\n" ); document.write( "The distance is equal, so:
\n" ); document.write( "3t = 12(t-3),
\n" ); document.write( "3t = 12t - 36,
\n" ); document.write( "36 = 9t,
\n" ); document.write( "t = 4.
\n" ); document.write( "That's twelve miles. \r
\n" ); document.write( "\n" ); document.write( "Part 2:
\n" ); document.write( "Similar to part 1:
\n" ); document.write( "d = 3t,
\n" ); document.write( "d = 39(t - 6);
\n" ); document.write( "so
\n" ); document.write( "3t = 39(t - 6),
\n" ); document.write( "3t = 39t - 234,
\n" ); document.write( "234 = 36t,
\n" ); document.write( "t = 6.5 (hours), that's 19.5 miles away when they meet! \r
\n" ); document.write( "\n" ); document.write( "Part 3:
\n" ); document.write( "The woman on foot no longer needs considered- the offset of the man-on-bicycle and woman-on-scooter is three hours:
\n" ); document.write( "d = 12t,
\n" ); document.write( "d = 39(t - 3); so,
\n" ); document.write( "12t = 39(t - 3),
\n" ); document.write( "12t = 39t - 117,
\n" ); document.write( "117 = 27t,
\n" ); document.write( "so the time for the man-on-bicycle is 4.333 hours (the woman-on-scooter takes 1.333 hours). \r
\n" ); document.write( "\n" ); document.write( "Either way, the distance is 52 miles.
\n" ); document.write( "
\n" );
