Turns Left: Now facing South, walks 5 km to reach point D.
Turns Left: Now facing East, walks 5 km to reach point E.

Finding the Distance

Since he was 4 km west of the starting line and walked 5 km back towards the east, he passes his starting line.
Distance = $5\text{ km} - 4\text{ km} = 1\text{ km}$.
