The pioneering engineering team built a winding mountain road. It was originally planned to build 12.5 meters per day and complete the task in 30 days. The actual number of meters repaired every day is 1.5 times the original plan. According to these data, please put forward some mathematical problems and answer them in parallel.
开拓工程队修一条蜿蜒的山路，原计划每天修12.5米，30天完成任务．实际每天修的米数是原计划的1.5倍．根据这些数据，请你提出一些数学问题，并列式解答．
