It should be 15 because 48/3.2 is 15 and that means he swam 48 kilometers in 15 days
Answer:
slope = 1/4
Step-by-step explanation:
If a equation is in form of y = mx + c
them m is the slope of line.

Let Y(d) be the distance ran by Alexandria on dth day
Y(0) = 2
she adds 1/4 miles each day then
Y(1) = 2 + 1/4
Y(2) = 2 + 1/4 +1/4 = 2 +1/4(2)
Y(3) = 2 + 1/4 +1/4 +1/4= 2 +1/4(3)
.

.
similarly
in d days she can run 2 miles + 1/4*d miles
thus, we have
Y(d) = 2 + 1/4(d)
it can be also solved
Thus we see that it is a linear relationship y = 2 + 1/4(d)
which is in the form of y = mx + c
comparing mx to 1/4 d
we have m = 1/4
thus,
slope of this linear relationship is 1/4
Answer:
Step-by-step explanation:
Given
The second fret is 
from the first fret.
The third fret is 
from the second fret.
Distance of third fret from the first fret 
Distance from first fret to second fret 
Distance from second fret to third fret.
Hence, we can see the third fret is from the first fret.
