Question: A thirsty traveler found an oasis in the desert. He drank 32 ounces of water. His camel drank seven times as much as he did. There are 128 ounces in a gallon. How many gallons of water did they drink altogether?
Solution:
The traveler’s camel drank 7 * 32 = 224 ounces of water.
Together, the traveler and his camel drank 32 + 224 = 256 ounces.
Thus, they drank 256 / 128 = 2 gallons of water altogether.
Answer: 2
