Answer:
-3.5
The distance Rachel covers per hour is 3.5 miles
Step-by-step explanation:
After 2 hours, she is 13 miles from the campground.
After 4 hours, she is 6 miles from the campground.
Let x be the number of hours, y be the number of miles from the campground, then we have two points (2,13) and (4,6).
The equation of the line passing through the points 
and 
is
Substitute:
Hence,
The slope of the line is 
and it represents that the distance Rachel covers per hour is 3.5 miles.

Answer:
3/110
Step-by-step explanation:
x = .0272727 repeating
Multiply by 100
100x = 2.727 repeating
Subtract the first equation from the second
100x = 2.727 repeating
-x = .0272727 repeating
------------------------------------
99x = 2.7
Divide each side by 99
99x/99 = 2.7/99
x = 27/990
x =3/110
