A toaster oven uses 67500 joules of energy in 45 seconds to toast a piece bread. What is the power oven?

$$P = \frac{E}{t}$$

Where:

- \(P\) is power in watts (W)

- \(E\) is energy in joules (J)

- \(t\) is time in seconds (s)

In this case, we have:

- \(E\) = 67500 J

- \(t\) = 45 s

So, the power of the toaster oven is:

$$P = \frac{67500 \text{ J}}{45 \text{ s}} = 1500 \text{ W}$$

Therefore, the toaster oven has a power of 1500 W.
