[Question]: Rachel is writing an essay. She writes 1 page every 30 minutes. She spends 45 minutes researching the topic. She writes a total of 6 pages. Then she spends 75 minutes editing her essay. Altogether, how many hours did she spend completing the essay?
[Answer]: She spends this long researching and editing her essay 45 min + 75 min = 120 min. Converting the minutes to hours for researching and editing is 120 / 60 = 2 hours. She spends this long writing the essay 6 x 30 min = 180 min. Converting the minutes to hours for writing the essay is 180 / 60 = 3 hours. The total hours Rachel spends completing the essay is 2 + 3 = 5 hours.
So the answer is 5.

[Question]: Marcy keeps a 2-liter bottle of water by her desk. She takes a sip every five minutes, and each sip is 40 ml. How many minutes does it take her to drink the whole bottle of water?
[Answer]: First find the total number of milliliters in the bottle: 2 liters * 1000 ml / liter = 2000 ml. Then divide the total number of milliliters by the amount she drinks per sip: 2000 ml / 40 ml = 50 sips. Then multiply the number of sips by the time per sip to find the time it takes her to drink the bottle: 50 sips * 5 minutes / sip = 250 minutes.
So the answer is 250.
