A recipe for 12 bran muffins calls for 1 cup of flour. the number of muffins that can be made varies directly with the amount of
flour used. There are 1 and 1/4 cups of flour available. How many muffins can be made?
2 answers:
12 muffins = 1 cup
x = 1 1/4 cups
x = 5/4 cups
cross multiply:
12*5 / 4 = x * 1
3 * 5 = x
x = 15
Answer = 15 Muffins
Other way:
1 1/4 cups = how many muffins
you already know 1 cup = 12 muffins
remaining 1/4 cups = how many muffins?
1/4 of 12 = 3
So 12 + 3 = 15 muffins
Fifteen muffins can be made.

Answer:
Starts at 6:15
Note: An hour is 60 minutes.
So an hour after 6:15 is 7:15 and an hour after that is 8:15. Now just add another 10 minutes and you get 8:25.
So the film ended at 8:25.
