Question

Water goes over Niagara Falls at a rate of 180 million cubic feet every 30 minutes. How much water goes over the Falls in 1 minute?

Answer 1

Answer: 6 million cubic feet

Explanation:

If there are 180 million cubic feet going over the Falls every 30 minutes, you can find the per minute rate by dividing the amount of water going every half hour by a half hour:

= Amount of water every 30 minutes / 30 minutes

= 180 / 30

= 6 million cubic feet
