Answer:

2 Hours

Step-by-step explanation:

1 hour is 4kg so if we add another hour, we add another 4kg, which is 8kg in 2 hours, hope this helped!
sadie worked 2 hours because if every 1 hour sadie makes 4 kilos of dough and she makes 8 kilos of dough and 4 + 4 = 8 so that means that she made another 4 kilos and she worked 2 hours
