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.

A reproductive combination between living parent organisms which produces hybrids is: c. when members of closely related species reproduce.
<h3>What is reproduction?</h3>
Reproduction can be defined as a biological process through which all living parent organisms produce their offspring, especially through mating.
<h3>What is a species?</h3>
A species is a biological classification of related organisms that have the same or similar characteristics, and they are capable of mating (breeding) with one another in a cycle or different seasons.
During the reproduction process, a reproductive combination between living parent organisms which would produce hybrids is usually when members of closely-related species reproduce.

Complete Question:
Which reproductive combination produces hybrids?
a. when individuals of the same species in different geographical areas reproduce
b. when any two individuals sharing the same habitat reproduce
c. when members of closely related species reproduce
d. when offspring of the same parents reproduce
Answer:
c. metal
Explanation:
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it.

Answer:
53 and 16
Explanation:
The answer is 53 for the first one because 25% of 212 is 53 so Kelly should read 53 pages a day to finish the book.\
Again the answer is 16 because 25% of 64 is 16 so there would be 16 ounces of milk left.
