D. When working with scales, always remember to convert. The dimensions of the actual forest become 8 X 15 and 14.5 X 15. To calculate the area, now just do: (8 X 15) X (14.5 X 15), which equals 26100.
So, to start off, find the total amount of words that there must be. 15 pages * 350 words per page = 5250 words total. 5250 words total / 70 words per minute = 75 minutes or about 1 hour and 15 minutes.
Reflecting an image/shape over the x axis is reflecting it over a horizontal line, so the x coordinates will stay the same and the y coordinates will be the opposite. Therefore, the answer is D. Hope this helps!
