I need help with my math question

Question

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?

Answer 1

Your must multiply the stated rate of cu ft per second by the number of seconds.

 

1 minute is 60 seconds; 60 min is one hour, so there are 3600 seconds per hour.

 

Then to find the discharge per year, use 24 hours times 365 days to get 1 year = 24(365)3600)(4,300,000) cu ft per year.

I'm letting you do the arithmetic.
