Motorcycle engine

The motorcycle engine has a constant power of 1.2 kW for 0.5 hours. How much work does the engine do? Express work in kWh and Ws units.

Correct result:

W1 =  0.6 kWh
W2 =  2160000 Ws

Solution:

P=1.2 kW t=0.5 h  W1=P⋅ t=1.2⋅ 0.5=35=35 kWh=0.6 kWh
W2=3600⋅ 1000⋅ W1=3600⋅ 1000⋅ 0.6=2160000 Ws
