Question

This Question: 1 pt Athough the actual amount varies by season and time of day, the average volume of water that flows over the fails each second is 3.3x 10 gallons. How much water flows over the falls in an hour? Write the result in scientific notation Mint 1 hour equals 3600 seconds) gions of water flows over the fats in an hour. Une multiplication symbol in the math palette as needed)

Answer 1

Solution:

Given,

In 1 second, the average volume of water that flows over the falls $=3.3\ \textup{x} \ 10^{5}$ gallons

Now, we need to find the volume of water that flows over the falls in one hour i.e. in 3600 seconds.

So, in 3600 seconds, the volume of water that flows over the falls

$=3600\ \textup{x} \ 3.3\ \textup{x} \ 10^{5}$ gallons

$=11880\ \textup{x}\ 10^{5}$ gallons

$=1.188\ \textup{x}\ 10^{4} \textup{x}\ 10^{5}$ gallons

$=1.188\ \textup{x}\ 10^{4+5}$ gallons

$=1.188\ \textup{x}\ 10^{9}$ gallons

Hence, $1.188\ \textup{x}\ 10^{9}$ gallons of water flows over the falls in an hour.
