Answer :
Final answer:
Sarai's displacement is found using the formula: Displacement = Speed x Time. With a speed of 1.2 m/s and a time of 1500s, her displacement is 1800 meters.
Explanation:
The subject of this question is one related to kinematics, an aspect of physics that uses equations to describe the motion of objects. In this case, we are trying to determine the displacement of a person named Sarai. Displacement can be calculated as the product of velocity (which is the same as speed in this case, since Sarai is moving in a single direction) and time.
Here, Sarai's given average speed is 1.2 m/s and the time she spends strolling is 1500 s. Therefore, her displacement can be calculated using the formula: Displacement = Speed x Time.
Carrying out this calculation, (1.2 m/s x 1500 s), we get her displacement to be 1800 meters. This means Sarai has moved 1800 meters to the right.
