According to figure
If a moves north in 100km in so 10 hrs
Now a will also move the same 100 km
Beacuse of them both is Same
But if we take 50km only then A will take same
Both will form right angle result displacement is 50root2 and it is short
Now so it is found 50km is shortest.
Time taken to establish it is 50÷10
So answee is 5 hours
