At 11 am Kate left clinton tollbooth travelling west at 809 km/h. At 12 pm, Juan left the tollbooth traveling west at 72 km/h. At what time will they be 98 km apart
\n" ); document.write( "----------
\n" ); document.write( "Kate DATA:
\n" ); document.write( "rate = 809 km/h ; time = x + 1 hrs ; distance = 809(x+1) km
\n" ); document.write( "------------------------------
\n" ); document.write( "Juan DATA:
\n" ); document.write( "rate = 72 km/h ; time = x hrs ; distance = 72x km
\n" ); document.write( "--------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "distance + distance = 98 km
\n" ); document.write( "809(x+1) + 72x = 98
\n" ); document.write( "809x + 809 + 72x = 98
\n" ); document.write( "---------------
\n" ); document.write( "These numbers give a negative answer.
\n" ); document.write( "Most probably the 809 km/h rate for Kate is wrong.
\n" ); document.write( "------------------------------
