 Solve the problem by setting up an equation:<br/>A school is renovating its track and field during the summer vacation. The project contractor sent the first construction team to start the construction and planned to complete the entire project in $30$ days. After working for $10$ days, the contractor received a notice that a large event was going to be held at the track and field. They were asked to complete the entire project $8$ days earlier than originally planned. Therefore, the contractor sent the second construction team to work together with the first team to finish the remaining work, and the entire project was completed on time as requested. If the second construction team worked alone, how many days would it take to complete the entire project? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
