\n" ); document.write( "---------
\n" ); document.write( "Jack DATA:
\n" ); document.write( "rate = 70 mph ; time = t-(3/2) hrs ; distance = r*t = 70(t-(3/2)) miles
\n" ); document.write( "-----------------
\n" ); document.write( "John DATA:
\n" ); document.write( "rate = 65 mph ; time = t hrs ; distance = r*t = 65t miles
\n" ); document.write( "---------------
\n" ); document.write( "Equation:
\n" ); document.write( "dist = dist
\n" ); document.write( "70t - 105 = 65t
\n" ); document.write( "5t = 105
\n" ); document.write( "t = 21 hrs
\n" ); document.write( "-----------------
\n" ); document.write( "t - (3/2) = 19.5 hrs (Jack's time)
