Answer:

Upstream = 0.5 hour.

Downstream = 0.366 hour.

Step-by-step explanation:

Speed of fram in still water (u) = 2.6 mph.

Speed of water (v) = 0.4 mph .

<h3>Time taken by fran to swim 1.1 mi upstream.</h3>

Speed upstream = u - v = (2.6 - 0.4)  mph = 2.2 mph

So the time taken = \frac{distance}{speed}  = \frac{1.1}{2.2} = 0.5 hour.

<h3>Time taken by fran to swim 1.1 mi downstream.</h3>

Speed downstream = u + v = (2.6 + 0.4) mph = 3 mph .

So the time taken = \frac{1.1}{3} =  0.366 hour .

Step-by-step explanation:

<u>Step 1: Define</u>

f(x) = 6x - 4

g(x) = -5x + 24

<u>Step 2: Find f(x) + g(x)</u>

  1. Substitute in functions:                                                                                     f(x) + g(x) = 6x - 4 + (-5x + 24)
  2. Combine like terms (x):                                                                                    f(x) + g(x) = x - 4 + 24
  3. Combine like terms:                                                                                         f(x) + g(x) = x + 20
