SUMMARY
The discussion focuses on calculating the distance a backpacker walks east after initially hiking west. The backpacker travels 6.44 km at an average velocity of 2.68 m/s due west, then turns around and hikes east at 0.447 m/s. The solution involves using the velocity formula to equate the time taken for each segment of the journey. The equation derived is (6440/2.68) + (x/0.447) = (6440-x)/1.34, which can be solved for the distance x walked east.
