Answer:
Explanation:
Unfortunately, I cannot answer this question without additional information about the distances traveled and the time taken by Reiko to travel from point A to point B and back to point A.
The speed at which Reiko traveled is calculated as distance divided by time. Therefore, we need to know both the distance and time for each leg of the journey to determine the speed.
Without this information, it is not possible to determine whether Reiko traveled from A to B at a speed greater than 40 miles per hour.
