\n" ); document.write( "Ryn left the museum and drove south. Gab left 3 hours later driving 42 km/h faster in an effort to catch up to him. After 2 hrs, Gab finally caught up. Find Ryn's average speed.
\n" ); document.write( "

Let Ryn’s speed be S
\n" );
document.write( "Then Gab’s speed = S + 42
\n" );
document.write( "As Ryn drove for 5 (3 + 2) hours, and Gab drove for 2 hours, we get the following DISTANCE equation:
\n" );
document.write( "5S = 2(S + 42)
\n" );
document.write( "5S = 2S + 84
\n" );
document.write( "5S – 2S = 84
\n" );
document.write( "3S = 84
\n" );
document.write( "S, or Ryn’s speed = , or  \n" );
document.write( "

\n" );
