13* This is the plan view of a corridor in a school building.

Figure for question 13

The arrow XY shows the path student A takes to walk around the corridor from Room 1 to Room 2

Student A takes 120 seconds to walk from point X to point Y. Student B describes the motion:

β€˜The average velocity of student A is greater than their average speed.’

β€˜This is because their displacement is greater than the distance they travel.’

Evaluate these statements.

Use calculations to help explain your answer.
