Correct answer 100%

Answer 2

The answer to your question is: t = 167 s

Step-by-step explanation:

Power is defined as a rate at which work is done. Its units are Watts (W). Then the formula to calculate Power is:

`P = (W)/(t)`

Data

Power = P = 1500 W

time = t = ?

Energy = W = 250000 J

Solve equation for time

`t = W / P`

Substitution

t = 250000 / 1500

Result

t = 166.67 ≈ 167 s
