Answer:
11.23%
Explanation:
Lets take
Speed of man in still water =u= 1.73 m/s
Speed of flow of water = v=0.52 m/s
When swims in downward direction then speed of man = u + v
When swims in upward direction then speed of man = u - v
Lets time taken by man when he swims in downward direction is and when he swims in downward direction is
Lets distance is d and it will be remain constant in both the case
Time taken in still water
2 d= t x 1.73
t=1.15 x d sec
total time in current = 0.82 +0.44 d=1.26 d sec
So the percentage time
Percentage time =11.32%
So it will take 11.32% more time as compare to still current.

Explanation:
<u>Displacement Vector</u>
Suppose an object is located at a position
and then moves at another position at
The displacement vector is directed from the first to the second position and can be found as
If the position is given as magnitude-angle data ( z , α), we can compute its rectangular components as
The question describes the situation where the initial point is the base of the mountain, where both components are zero
The final point is given as a 520 m distance and a 32-degree angle, so
The displacement is
