A batch of coal was transported into the boiler room, and last year it burned 0.8 tons per day, which lasted for 60 days. This year, the technicians have improved the boiler to burn 0.6 tons per day. How many days can the same batch of coal be burned this year?
锅炉房运进一批煤，去年每天烧0.8吨，可以烧60天．今年技术员对锅炉进行了改进，每天烧0.6吨，同样一批煤今年可以烧多少天．
