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:
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.
I’d say F. While weather distracting you is dangerous, if your tires are worn down it’s really dangerous to drive with. They can cause steering problems and can make you skid. Plus it increases the chances of a blowout. Plus the weather distracting you won’t happen every time you drive.
Using previously given equation, the estimate of the GPA of a student who studies for 15 hours a week is; 3.1
<h3>How to predict an equation?</h3>
The equation here is probably a "best fit" equation based upon given data which is GPA versus the number of hours of study per week.
Now, the equation of best fit is given as;
y = 0.149x + 0.89
Thus, if the number of study hours of interest is 15, then the GPA is;
GPA = 0.149(15) + 0.89
GPA = 3.1

What is kingdom of Eubacteria.
Explanation:
Streptococci are bacteria which are gram-positive in nature.
This organism belongs to the kingdom eubacteria since this kingdom is characterized by the following features that are also present in streptococcus:
1. Unicellular organism.
2. prokaryotic.
3. presence of cell wall made up of peptidoglycans.
