Work Rate Problems
At 8:00 am, Sarah began working on a project by herself. After completing a 10-hour shift, which included a 1-hour break for lunch, she managed to finish part of her work. The following day, she returns at the same time, but this time she is joined by her coworker, Tom, who assists her in completing the project by 4:00 pm. Since they finished the task before the end of their shift, neither took a lunch break. If Tom can finish the entire project in 12 hours, how long would it take Sarah to finish the project if she worked alone?
