The clock in a certain factory slows down, so that the minute hand and the hour hand coincide once every 70 minutes in standard time. Master Li works at this slow clock for 8 hours. The factory stipulates that the overtime wage is 3.5 times higher than the original salary. Master Li’s original wage is 3 yuan per hour.
