Bucket K has five times as much water as Bucket J. If Nick adds 0.7 ℓ of water to Bucket K and 2.5 ℓ of water to Bucket J, both buckets will have the same volume of water. Find the volume of water in Bucket K at first.
| |
J |
K |
| Before |
1 u |
5 u |
| Change |
+ 2.5 |
+ 0.7 |
| After |
1 u + 2.5 |
5 u + 0.7 |
Both buckets have the same volume of water in the end.
5 u + 0.7 = 1 u + 2.5
5 u - 1 u = 2.5 - 0.7
4 u = 1.8
1 u = 1.8 ÷ 4 = 0.45
Volume of water in Bucket K at first
= 5 u
= 5 x 0.45
= 2.25 ℓ
Answer(s): 2.25 ℓ
