Tucker and jane have an apple stand infront of their farm. Due to the fact that a road crew is nearby, they average 50 customers per hour. If Tucker and Jane work separately, each can help a customer in 52 seconds, on average. (Assume that customers form one line to be served by Tucker or Jane, depending on who becomes available.) What is the average total time for a customer to get their lemonade (including waiting in line and being served),in minutes? (Provide number only, round to two decimal places).
