An engineering team built a railway tunnel. When (1/3) of the task was completed, the engineering team adopted new equipment, which increased the construction speed by 20%. At the same time, in order to maintain the new equipment, the daily working hours were shortened to the original (4/5 ), as a result, it took 185 days to complete the project. From the above conditions, it can be deduced how many days it will take to complete the project if new equipment is not used.
某工程队修建一条铁路隧道，当完成任务的(1/3)时，工程队采用新设备，使修建速度提高了20%，同时为了保养新设备，每天工作时间缩短为原来的(4/5)，结果，前后共用185天完工，由以上条件可推知，如果不采用新设备，完工共需多少天．
