Can you help me please?

A slice of pizza contains about 290 Calories, which is equal to about 1200 Kilojoules. If you burned your pizza as fuel to power an oven with a 1000W output, how long would one slice power this oven? Assume complete conversion of pizza energy to oven energy. Enter your answer in minutes, without including the units.

a Watt is a Joule per second

1000 W is 1kJ/s

1200 kJ means 1200 seconds at 1000 Watts
