Eight minutes after a bank was robbed, the police started a chase to pursue the thief. The thief was driving at 70 km./hr., while the police were driving at 90 km./hr. How long did it take the police to catch up with the thief?\r
\n" ); document.write( "\n" ); document.write( "Thief DATA:
\n" ); document.write( "distance=?; rate=70km/hr; time= x minutes\r
\n" ); document.write( "\n" ); document.write( "Police DATA:
\n" ); document.write( "distance=?; rate=90km/hr; time = x-8 minutes\r
\n" ); document.write( "\n" ); document.write( "Conversion formula: distance = (rate)(time)\r
\n" ); document.write( "\n" ); document.write( "EQUATION:
\n" ); document.write( "thief distance = police distance\r
\n" ); document.write( "\n" ); document.write( "70x=90(x-8)

\n" ); document.write( "-20x=-720
\n" ); document.write( "x=36 minutes
