\n" ); document.write( " Find the number of hours Shayna drove before Mei caught up
\n" ); document.write( ":
\n" ); document.write( "Let t = S's travel time when M caught up
\n" ); document.write( ":
\n" ); document.write( "Find the distance driven by M:
\n" ); document.write( "4 * 65 = 260 mi
\n" ); document.write( "This is also the distance driven by S, when she is caught
\n" ); document.write( ":
\n" ); document.write( "52t = 260
\n" ); document.write( "t = 260/52
\n" ); document.write( "t = 5 hrs, S's travel time when caught by M
