The answer in terms of pi would be 13.3225pi. And the full answer would be 41.83265.
Answer:
10 min = 1/6 hour
Now we make Andrew's average speed v mph so Katherine's average speed is (v-2) mph
a. 8/v - 5/v-2 = 1/6 [distance = speed x time]
b. 8/v - 5/v-2 = 1/6 , v > 2
8/v - 5/v-2 = 1/6 = 0
48(v-2) -30v-v-(v-2)/6v(v-2) = 0 [transform the expression]
20v-96-v^2/6v(v-2) = 0
20v-96-v^2 = 0
(v-8)(v-12) = 0
{v1=8}
{v2=12}

Answer: Choice A</h3>
y axis, x axis, y axis, x axis
============================
Explanation:
Reflecting an object over the y axis twice will have it end up in its starting position. The same can be said for the x axis as well. It doesn't matter that the x axis reflections aren't grouped next to each other, nor the y. So in a sense, two x axis reflections undo each other, so do the y axis reflections, and we end up with the same image as shown in the diagram.
