An 82-year-old man is on the palliative care ward.

An 82-year-old man is on the palliative care ward. He was currently being treated with 40mg oral morphine OD however due to side effects the decision is made to switch to an IV infusion of morphine. It is decided he should receive this dose over a 3-hour period to control his pain. IV Morphine is currently available at 10mg/ml solution. 

Please give the infusion rate (up to 2 decimal places), per hour, of morphine this gentleman should receive.
