The basic formula required is \"d=rt\".
\n" ); document.write( ":
\n" ); document.write( "We know the distance to be 40km and the time to be 15 minutes or 0.25 hour, so if \"d=rt\", then
\n" ); document.write( "\"r=d%2Ft\"
\n" ); document.write( "\"r=40%2F0.25\"
\n" ); document.write( "\"r=160kmph\"
\n" ); document.write( ":
\n" ); document.write( "\"d=rt\"
\n" ); document.write( "\"d=160t\"
\n" ); document.write( ":
\n" ); document.write( "if \"d=rt\", then \"t=d%2Fr\", so:
\n" ); document.write( "\"t=360%2F160\"
\n" ); document.write( "\"t=9%2F4\"hours, or 1 hour and 45 minutes after she passes St. Catherines. 1 hour and 45 minutes after 12:15 is 2:00 PM.\r
