Answer:

The approximate number of gallons of water that flow over the waterfall in 1 day is:

  • A. 5.59 x 10^10

Step-by-step explanation:

To obtain the answer to the question, you must multiply the number gallons of water flow over a waterfall each second (6.5 x 10^5 gal/s) by the number of seconds in a day (8.6 x 10^4 s), as I show you below:

  • Gallons of water that flow over the waterfall in 1 day = Number of gallons * Number of seconds in a day.
  • Gallons of water that flow over the waterfall in 1 day = 6.5 x 10^5 gal/s * 8.6 x 10^4 s

Now, we must cancel the seconds, then:

  • Gallons of water that flow over the waterfall in 1 day = 5.59 x 10^10 gallons

How you can see, once you have multiplied these two values, the answer is the same to the option A.
