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:
Answer:

1 ice cream cone: $2.75
2 ice cream cones: 2 * $2.75 = $5.50
7.5% of $5.50 =
= 0.075 * $5.50
= $0.4125
Answer: $0.41
If n is an even integer:
n(n + 2) = 48
n^2 + 2n - 48 = 0
(n + 8)(n - 6) = 0
n = -8 or n = 6
Answer:
61
