An airplane left an airport flying at at 180 mph. A jet that flies at 333 mph left 1 hour later. The jet follows tthe same route as the airplane on parallel altitudes. How many hours will it take the jet to catch up with the airplane?

\n" ); document.write( "This problem needs you to apply the \"distance formula\":
\n" ); document.write( "d = rt
\n" ); document.write( "where
\n" ); document.write( "d is distance
\n" ); document.write( "r is rate or speed
\n" ); document.write( "t is time
\n" ); document.write( ".
\n" ); document.write( "\"distance airplane traveled\" = \"distnce jet traveled\"
\n" ); document.write( ".
\n" ); document.write( "Let x = hours \"airplane\" was flying
\n" ); document.write( "x-1 = hours \"jet\" was flying
\n" ); document.write( ".
\n" ); document.write( "180x = 333(x-1)
\n" ); document.write( "180x = 333x - 333
\n" ); document.write( "180x + 333 = 333x
\n" ); document.write( "333 = 153x
\n" ); document.write( "333/153 = x
\n" ); document.write( "2.176 hours = x
