Container V has five times as much water as Container U. If Sean adds 0.7 ℓ of water to Container V and 2.9 ℓ of water to Container U, both containers will have the same volume of water. Find the volume of water in Container V at first.
| |
U |
V |
| Before |
1 u |
5 u |
| Change |
+ 2.9 |
+ 0.7 |
| After |
1 u + 2.9 |
5 u + 0.7 |
Both containers have the same volume of water in the end.
5 u + 0.7 = 1 u + 2.9
5 u - 1 u = 2.9 - 0.7
4 u = 2.2
1 u = 2.2 ÷ 4 = 0.55
Volume of water in Container V at first
= 5 u
= 5 x 0.55
= 2.75 ℓ
Answer(s): 2.75 ℓ
