Final answer:
The statement about the speeds of Person X and Person Y is false; X is actually moving at twice the speed of Y. Additionally, the displacements of the two individuals walking different paths but the same total distance are the same.
Step-by-step explanation:
The statement that Person Y is moving with twice the speed as person X is false. If Person X moves from location A to location B in 5 seconds and Person Y moves between the same two locations in 10 seconds, this actually indicates that Person X is moving at twice the speed of Person Y, since they cover the same distance in half the time.
To address the other elements of this student's set of questions, it is false that if a person walks 2 blocks east and 5 blocks north and another person walks 5 blocks north and then 2 blocks east, their displacement will be different. Displacement is independent of the path taken; it only depends on the initial and final position. Thus, the displacement for both individuals is the same because they start and end at the same locations.
