Explanation:
The concept we're dealing with here is rate. Rate is a type of proportion that compares two quantities in different units. In this case, the rate is the number of pages Gianna reads per hour. We calculated this by dividing the number of pages she read (31) by the time in hours she read for (2/3), to get the rate of 46.5 pages per hour . Hence, if Gianna continues to read at the same rate, she will read 46.5 pages in one hour. Therefore, the answer is A. 46.5 pages.
