Answer:
In 3 seconds the cup is filled with <u>.</u>
Step-by-step explanation:
Given:
2 seconds = water
We need to find the percent of the cup that is filled with water after 3 seconds.
Solution:
Now Given:
The cup was filled at a constant rate.
First we will find the volume of water filled in the cup after 1 seconds.
2 seconds = water
1 seconds = Volume of water filled in 1 second.
By Using Unitary method we get;
Volume of water filled in 1 second =
Now we will find the volume of water filled in the cup after 3 seconds.
1 second = of water is filled
3 seconds = volume of water filled in the cup after 3 seconds
Again by using Unitary method we get;
volume of water filled in the cup after 3 seconds =
Hence In 3 seconds the cup is filled with .
To find the percent of the cup filled with water after 3 seconds we would required the dimensions of the cup which is not available in the question.
