Party A and Party B have built canals. The ratio of planned canals is 3:2. When the project is completed, Party A has built 5 / 12 of the total canals, and Party B has built 209 meters more than planned, so the total length of canals is required
Party B plans to repair 2 (3 + 2) = 2 / 5
Actually 1-5 / 12 = 7 / 12
So the total length is 209 (7 / 12-2 / 5) = 1140m
Party A and Party B jointly build a canal. The ratio of meters planned by Party A and Party B is 3:2. When the project is completed, Party A will build 512 meters of the total length, and Party B will build 209 meters more than planned. What is the total length of the canal?
A: the total length of the canal is 1140 meters
