A complete underground mining cycle includes: $(1)$ move broken ore to station; $(2)$ drill $408-$foot holes, $(3)$ insert ammonium nitrate, $(4)$ light fuze and leave. In $1986$ mine manager Noyes calculated the learning rate and first day cycle time hours. He would like you to use this information to forecast what the new cycle time would be on the $25$ th day, and to determine the total hours required to complete $25$ cycles.
