Answer:

4.5 seconds

Step-by-step explanation:

For this question, we're gonna use the formula below:

Power = Work / Time

where Power is measured in watts (W), Work is measured in joules (J), and Time is measured in seconds (s).

To solve for Time, we can rearrange the formula as follows:

Time = Work / Power

Now, we need to find the amount of work done in pushing the box:

Work = Force x Distance

where Force is measured in Newtons (N) and Distance is measured in meters (m).

So,

Work = 50 N x 27 m = 1350 J

Now we can substitute the values into the formula for time:

Time = Work / Power = 1350 J / 300 W = 4.5 s

Therefore, it will take 4.5 seconds for the person to push the 50 N box 27 meters using 300 watts of power.
