Tank E has five times as much water as Tank D. If Daniel adds 0.6 ℓ of water to Tank E and 2.4 ℓ of water to Tank D, both tanks will have the same volume of water. Find the volume of water in Tank E at first.
| |
D |
E |
| Before |
1 u |
5 u |
| Change |
+ 2.4 |
+ 0.6 |
| After |
1 u + 2.4 |
5 u + 0.6 |
Both tanks have the same volume of water in the end.
5 u + 0.6 = 1 u + 2.4
5 u - 1 u = 2.4 - 0.6
4 u = 1.8
1 u = 1.8 ÷ 4 = 0.45
Volume of water in Tank E at first
= 5 u
= 5 x 0.45
= 2.25 ℓ
Answer(s): 2.25 ℓ
