Answer:

  22 miles per hour

Step-by-step explanation:

Against the current, the boat's rate of travel is ...

  (120 mi)/(6 h) = 20 mi/h

With the current, the boat's rate of travel is ...

  (120 mi)/(5 h) = 24 mi/h

___

The sum of boat speed (b) and current speed (c) is 24 mph. The difference is 20 mph. This lets us write the equations ...

  b + c = 24

  b - c = 20

Adding these two equations together, we get ...

  2b + 0c = 44

  b = 22 . . . . . . . . divide by 2

The rate of the boat in still water is 22 miles per hour.

Find the value of x ANSWER IS NOT
gulaghasi [49]

Answer:

x = 11√2

Step-by-step explanation:

We can notice the triangle given is a special triangle, a 45°- 45°- 90° triangle. The hypotenuse of a 45°- 45°- 90° is √2 times the length of a side. We can set up the equation(using x as the side):

x * √2  = 22

We can divide by √2 on both sides to get:

x = 22 / √2

To rationalize the denominator, we multiply by √2 / √2 on the right side:

x = 22√2 / 2

This simplifies to:

x = 11√2
