Answer:
<em>2.5</em>
Step-by-step explanation:
y2 - y1 = top
x2 - x1 = bottom
<em>y2 = -5</em>
<em>y1 = -7.5</em>
<em />
<em>x2 = -2</em>
<em>x1 = -3</em>
<em />
<em />
-5-(-7.5) = 2.5
-2-(-3) = 1
2.5 over 1 = 2.5

Answer:
15 miles
Step-by-step explanation:
Let
be the miles in the circular park path,
the time Louisa takes to finish and
the time Calvin takes to finish both in hours.
Then
, the longitude is equal to the velocity times the time used to finish. So


And the difference between Louisa's time and Calvin' time is 30 minutes, half an hour. So:

Three equations, three unknowns, the system can be solved.
Equalizing the equation with x :

In this last equation replace
with the other equation and solve:
With Louisa's time find x:
