The 700-watt gasoline engine can do the work faster than the 300-watt electric motor because it has a higher power output. This means that for the same amount of work (3 J), the gasoline engine will take less time to complete it compared to the electric motor. Specifically, the gasoline engine requires approximately 0.00429 seconds, while the electric motor takes about 0.01 seconds.
