The average discharge at the mouth of the Amazon River is 4,300,000 cubic feet per second. How much water is discharged from the Amazon River in one hour? in one year?

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.
