A) 7:30 pm
B) 7:15 pm
C) 7:45 pm
D) 7:20 pm
Correct Answer: B
Solution :
Time taken by each pan to bake= 15 minutes. Number of pans cooked at a time = 2 Total number of pans = 12 Thus, Rory will have to take 6 rounds of baking his cookies if 2 pans are cooked simultaneously. And 6 pans X 15 minutes will take 1 hour 15 minutes. He starts at 5:45 pm so after 1 hour 15 minutes i.e at 7:15 he can close his shop after making all the cookies.You need to login to perform this action.
