\n" ); document.write( "I'll assume 30 mts means 30 minutes = 0.5 hours
\n" ); document.write( "---
\n" ); document.write( "d = r*t
\n" ); document.write( "r = slower rate
\n" ); document.write( "3*(t+0.5) = 4t
\n" ); document.write( "3t + 1.5 = 4t
\n" ); document.write( "t = 1.5 hours
\n" ); document.write( "----
\n" ); document.write( "d = 4t = 6 km
