1 answer:
Answer:
Upstream 1.1 hours and down stream 0.6875 hours.
Step-by-step explanation:
Jen motorboat travels at a speed of 13 mph in still water.
Now, the speed of river flows is 3 mph.
Therefore, the upstream speed of the boat is (13 - 3) = 10 mph and the downstream speed of the boat will be (13 + 3) = 16 mph.
Therefore, to travel 11 miles upstream Jen will take hours.
And to travel 11 miles down stream Jen will take hours. (Answer)

Step-by-step explanation:
Given that alpha and beta be conjugate complex numbers
such that frac{\alpha}{\beta^2} is a real number and alpha - \beta| = 2 \sqrt{3}.
Let
since they are conjugates
Imaginary part of the above =0
i.e.
So the value of alpha =
