Let the speed of the woman be x km/hr and the speed of the stream be y km/hr.
When the woman rows upstream, her effective speed is (x - y) km/hr. Given that she rows upstream at 16 km/hr, we have:
x - y = 16
When the woman rows downstream, her effective speed is (x + y) km/hr. Given that she rows downstream at 26 km/hr, we have:
x + y = 26
Now, we can solve these two equations simultaneously to find the values of x and y.
Adding the two equations together, we get:
2x = 42
x = 21
Substitute the value of x back into one of the equations, we get:
21 + y = 26
y = 5
Therefore, the speed of the stream is 5 km/hr.
