In this scenario, it is most likely that Casey will be able to walk at a faster pace and with less effort compared to Sarah. Since Casey regularly performs aerobic and anaerobic workouts, her cardiovascular fitness and endurance levels are likely to be higher. As a result, Casey will have greater stamina and be able to maintain a brisk walk for a longer duration. Sarah, on the other hand, being out of shape and having never worked out before, may struggle with the walk, experience fatigue quickly, or may need to take breaks during the mile walk.
