Answer:
A
Step-by-step explanation:
Area of rectangle = l x w
A = ac
Area of circle = πr^2
r = d/2 = b/2
b = semicircle = half of normal circle
A = π + ac
Recall your d = rt.
so hmm is about the same as the other one... so say the boat has a speed rate of "b", well, going downstream the boat goes say " b + 2 ", because the current is adding to it, and going upstream is " b - 2 " because the current is eroding from it.
So if the whole trip took 14 hours, say it took "t" hours going upstream, then going downstream it took the slack or " 14 - t ".
Also notice, the trip forth and back is the same 45 miles.
