A man takes 3 hours for the round trip from home to his farm and back along the same route. Going to the farm, he walks on a flat section, then uphill. The flat section is twice as long as the hilly section. His constant speeds are: flat 4 km/h, uphill 3 km/h, downhill 6 km/h. Find the total daily round-trip distance in km.
