Pls help me solve using Sing Math:
Joey and Ted’s jobs are to construct fences. Mrs. Merrick wants them to make a fence for her. She is going to pay the worker who works faster, higher. It takes Joey 9 hours longer to construct a fence than it takes Ted. If they work together, they can construct the fence in 20 hours. How long would it take each working alone to construct the fence?
