Answer:what are the choiese
Step-by-step explanation:
Answer: 60 miles
Step-by-step explanation:
Given
It takes ferry 2 hours to travel to town A and only
to travel back to town B.
Speed of current is 
Suppose the speed of the ferry is
mph
Distance traveled in both the cases is same, but it took more time traveling to city A that is, ferry is moving upstream and downstream for returning time.

Distance between the towns is 
The drawbridge will be at an incline of 10.56 degrees. That is 5.56 degrees more than it's initial incline of 5 degrees.
If you draw a picture of this situation, you will see that you can write a sine ratio with the 11 and 60 (opposite over hypotenuse)
sin(x) = 11/60 Solve the equation for x
x = 10.56
