Answer:

Step-by-step explanation:

Power is expressed as P = Force * Distance/time

From the formula given, the following parameters is needed to calculate power

1) Work done

2) force

3) Distance

4) Time

From the question, the given data is incomplete. We are supposed to be given the time taken to moved the chair over the distance. with the time we can easily calculate the power used up by the student.
