For this case we have the following equation:

We must clear the value of the variable "x" as a function of r, s and t:
If we multiply by "r" on both sides of the equation we have:

If we subtract "t" on both sides of the equation we have:

If we divide by "2" on both sides of the equation we have:

Thus, the value of the variable "x" is:

Answer:
<em>The speed of a boat in still water is 6 miles per hour. </em>
Step-by-step explanation:
t =
(upstream)
t =
(downstream)
=
40 ( s - 2 ) = 20 ( s + 2 )
40s - 80 = 20s + 40
20s = 120
s = 6 mi / h
<em>The speed of a boat in still water is 6 miles per hour.</em>
Total pets = 3+2 =5.
Total money = $22
Money for each pet would be:
22/5 in fraction .
$4.40 in dollars & cents.
