The table represents the distance covered by Emma over several hours on a recent Saturday bike ride. Becky takes the same route, and the total distance she travels, y miles, in x hours is represented by the function y = 8x. Assuming that Emma and Becky travel at a constant rate of speed, which statement BEST compares their biking speeds?

B Becky travels 0.5 miles per hour faster than Emma.Becky travels 0.5 miles per hour faster than Emma.
C Emma travels 7 miles per hour faster than Becky.Emma travels 7 miles per hour faster than Becky.
D Emma and Becky travel at the same speed.

The table representing Emma's distance covered over several hours does not provide any information about her speed. The table only tells us the distance covered in each hour, not how long it took Emma to cover that distance. Therefore, we cannot determine Emma's speed based on the given information. The correct answer is (D) Emma and Becky travel at the same speed.
