Power is equal to work divided by time
Work is equal to force times distance.

Explanation:

What I would do to solve your problem is to change 35 minutes to seconds. (35 x 60 = 2100). next I would divide 6,750,000 by 2100 = 3214.29. I think this answer is in watts so divide it by 1000 to get it into kilowatts. (3.21429)
