In order to solve this sum, you need the basic understanding of directions. You can refer to the image attached for better understanding.
Firstly the man moves 5km due east, and then 3km towards right i.e. due south and then 1km due west.
At this point of time you see the image, you can form a right angle triangle with base = 4km and perpendicular = 3km.
now we're asked to find his displacement from the starting point, that is nothing but the hypotenuse.
Therefore, required distance = ( 4^2 + 3^2 ) ^ 0.5 i.e. square root of the sum of squares of 4 and 3.
Now, I guess it's pretty easy to solve and you'll get the answer as 5km. Still, if you face problem refer the image.
The man is 5km away from the starting point towards the south-east.
