Hi, thank you for posting your question here at Brainy.
The path of the watercraft and the water current, when joined by a line forming a right angle would make a right triangle. From here, we can know the component in which it is along the same direction with the watercraft. Let's denote this as x.
x = 6 miles/h * cos 75 degrees
x = 1.55 miles/h
Thus, the actual speed = 70 + 1.55 = 71.55 miles/h

Poorly phrased question, but the general answer is 5k/(12k), where k <span>∈ Z (i.e. k is an integer).
So, 5/12 and 10/24.</span>
A ratio that is equivalent to 8/3 is 16/6.
Because:- 8*2= 16
3*2=6
16/6 is equivalent to 8/3
Writing a proportion:-
8/3=16/6
Assuming that the triangle is a right triangle, we can reverse engineer the Pythagorean theorem (a^2+b^2=c^2).
60^2 + x^2 = 61^2
3600 + x^2 = 3721
x^2 = 3600 - 3721
x^2 = 121
x = sqrt121
x = 11
