Note : The dimensions of the cup are not given.
Now we have been given that, after 2 seconds, the cup has a volume of 70 cubic cm.
As the cup is filled at a constant rate, in 1 second, it fills
[tex]\frac{70}{2}=35[/tex] = 35 cubic cm.
Hence, in 3 seconds, it fills [tex]35\times3=105[/tex] cubic cm.
To find the percent we need the dimensions of the cup.
The percentage of the cup that is filled with water after 3 seconds is 105 cm^3.
What is the unitary method?
The unitary method is a process by which we find the value of a single unit from the value of multiple units and the value of multiple units from the value of a single unit.
The cup was filled at a constant rate. it started empty. after 2 seconds, it held 70 cm of water.
The cup was filled at a constant rate.
first, we will find the volume of water filled in the cup after 1 second.
2 seconds = 70 water
1 second = Volume of water filled in 1 second.
By Using the Unitary method we get;
The volume of water filled in 1 second = 70/2 = 35
Now we will find the volume of water filled in the cup after 3 seconds.
1 second = 35 of water is filled
3 seconds = volume of water filled in the cup after 3 seconds.
The volume of water filled in the cup after 3 seconds = [tex]35\times 3=105[/tex].
Hence, the percentage of the cup that is filled with water after 3 seconds is 105 cm^3.
