For this question, an approach would be to convert kJ/min into kW (kJ/s), which is done by dividing the value by 60 seconds. 1 kW is equal to 1.34102 horsepower, so multiply the result by 1.34102.

The answer is in 3 significant figures because the question gives the value in 3 significant figures.
