The chart consists of 4 rows and 3 columns with r*t=d filling the three columns. Hope that makes sense.\r

Kathleen and Cade leave simultaneously from the same point hiking in opposite directions, Kathleen walking at 4mph and Cade at 5mph.
\n" ); document.write( "How long can they talk on their walkie-talkies if the walkie-talkies have a 20 mile radius???
\n" ); document.write( "----
\n" ); document.write( "Kathy DATA:
\n" ); document.write( "rate = 4 mph ; time = x hrs ; distance = 4x miles
\n" ); document.write( "----
\n" ); document.write( "Cade DATA:
\n" ); document.write( "rate = 5 mph ; time = x hrs; distance = 5x miles
\n" ); document.write( "----
\n" ); document.write( "Equation:
\n" ); document.write( "dist + dist = 20 miles
\n" ); document.write( "4x + 5x = 20
\n" ); document.write( "9x 20
\n" ); document.write( "x = 2.22 hrs = 2hr 13.2 minutes
\n" ); document.write( "------
\n" ); document.write( "That's how long they can talk.
