Question

McDonald's has a leaking drink machine. The manager placed a cup under the leak until he

could get it fixed. After 1 1/4 hours, the manager noticed that the cup had collected 1/3 cups of
soda. What is the rate, in cups per hour, at which the drink machine is leaking?

Answer 1

4/15 cups of soda per hour

Explanation:

1 1/4 = 5/4 and if 5/4 hours yielded 1/3 cups, you would have to multiply 1/3 by the reciprocal to find the hourly rate

1 4 4

- * - = --

3 5 15
