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.

When the spring is stretched to 11.0 cm - 8.0 cm = 3.0 cm = 0.030 m away from equilibrium, it stores
1/2 (150 N/m) (0.030 m)² = 0.0675 J
of potential energy, while stretching it to 14.0 cm - 8.0 cm = 6.0 cm = 0.060 m from equilibrium stores
1/2 (150 N/m) (0.060 m)² = 0.27 J
Then the change in potential energy is 0.27 J - 0.0675 J = 0.2025 J ≈ 0.21 J

There has been several evolution overtime. The one that tells how we understand the identities of Superman suggests that society's view of identity is known to be subjective.
- Here, the society takes identity at face value instead of the use of other form of evidence.
<h3>Why a subjective view?</h3>
From the study of the Superman's secret identity and its evolution, it therefore shows how the society really see the idea about identity.
Note that Clark Kent in the story has the same resemblance to Superman but they are of two identities types.
People often can see and accept one of the identity type they conform to them and ignore any kind of anomaly such as that of superman. So we can say that they are two different persons living two different lives.
