The recommended time for the french fries to be fully cooked is 5 minutes, which is equal to 5 x 60 = 300 seconds.
Bill put the french fries in the oven for 45 seconds.
To find out how many seconds remained, we subtract the time Bill put the french fries in from the recommended time. 
So, 300 seconds - 45 seconds = 255 seconds remained.
