The units of measure will help you understand what to do.
\n" ); document.write( "You want an answer in terms of time, specifically in terms of hours.
\n" ); document.write( "You know the vehicle is traveling at 80 km/hr.
\n" ); document.write( "You know the vehicle travels 210 km.
\n" ); document.write( "So, to end up with answer in hrs, you need to divide 210 km by 80 km/hr.
\n" ); document.write( ".
\n" ); document.write( "You also could apply the fundamental distance equation:
\n" ); document.write( "d = r*t
\n" ); document.write( "t = d/r
\n" ); document.write( ".
\n" ); document.write( "210/80 = 21/8 = 2 5/8 hr
\n" ); document.write( ".
\n" ); document.write( "5/8 hr * 60 min/hr = 300/8 min = 37.5 min
\n" ); document.write( ".
\n" ); document.write( "t = 2 hr 37.5 min
\n" ); document.write( ".
\n" ); document.write( "Done. \n" ); document.write( "

\n" );
