sorry but i think this is mistake
The distance between the campsite and the rest area is 9 miles.
The given parameters:
- <em>Initial speed of the campers, u = 4.5 mph</em>
- <em>Final speed of the campers, v = 4 mph</em>
<em />
Let the time of motion from the campsite to rest area = t (hours)
Time for return trip = t hours + 15 mins
= (t + 0.25) hours
Let the distance between the campsite and rest area = d
d = 4.5t
d = 4(t + 0.25)
4.5t = 4(t + 0.25)
4.5t = 4t + 1
4.5t - 4t = 1
0.5t = 1
t = 2 hours
The distance between the campsite and the rest area is calculated as follows;
d = 4.5t
d = 4.5 x 2
d = 9 miles
Thus, the distance between the campsite and the rest area is 9 miles.

Answer:
I find this question really interesting, and id love to give you my perspective on the pros of knowing how to calculate, discounts, sales taxs and
ect!
Explanation:
Why I believe it is important to know how to calculate on your own, there can be cases where an item is on sale for x% off, maybe a store clerk doesnt include the discount, by knowing how to calculate what percentage was supposed to be taken off of the item you can tell the clerk!
of if you were to work in a store you would need to calculate discounts too even though we have the technology doesnt mean it always works or is right, its a good back up!
There are many instances where, you being the costumer or clerk should know what discounts you are getting,or giving, its just percaution for the future!
~ hoped this helped!!
The graphical solution procedure generally means you graph the constraint inequalities to identify the feasible solution region, then locate the objective function curve so as to maximize its value. When the objective function is a linear function, maximizing it generally means locating it at the vertex of the feasible region that makes it farthest from the origin.
The solution is
... (A, B) = (100, 50)
