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.

Tju [1.3M]
The sides of the smaller window is 20 inches long.

An equation that represents this situation is shown below, where s is the length of the smaller window
1,025 = (5 + s)^2 + s^2

if s = 20 m, then:
(5 + 20)^2 + 20^2
= 625 + 400
= 1,025
