Pail U has thrice as much water as Pail T. If Ian adds 0.6 ℓ of water to Pail U and 1.5 ℓ of water to Pail T, both pails will have the same volume of water. Find the volume of water in Pail U at first.
| |
T |
U |
| Before |
1 u |
3 u |
| Change |
+ 1.5 |
+ 0.6 |
| After |
1 u + 1.5 |
3 u + 0.6 |
Both pails have the same volume of water in the end.
3 u + 0.6 = 1 u + 1.5
3 u - 1 u = 1.5 - 0.6
2 u = 0.9
1 u = 0.9 ÷ 2 = 0.45
Volume of water in Pail U at first
= 3 u
= 3 x 0.45
= 1.35 ℓ
Answer(s): 1.35 ℓ
