Gregory drinks 6 liters of water over 2 days. in how many days would he consume another 12 liters?

He would consume another 12 liters in 4 days. he drank 6 liters in two days so double 2 days and 6 liters to get 12 liters in 4 days.

What are the choices

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
