Answer: 7.5 miles per hour
Step-by-step explanation:
First speed was 3 miles per hour.
Second speed was 12 miles per hour.
To do an average, add both speeds and divide by two, which is the number of trips made.
= (3 + 12) / 2

Answer:
(x - 10)^2 + (y - 7)^2 = 2^2
Step-by-step explanation:
Start with the standard equation of a circle with center (h, k) and radius r:
(x - h)^2 + (y - k)^2 = r^2
Substitute 10 for h, 7 for k and 2 for r, obtaining:
(x - 10)^2 + (y - 7)^2 = 2^2
