Kant and the concept of “duty”

In his explication of the concept of duty, Kant claims that there is a distinction between things done in accordance with duty (whether from immediate inclination or without such inclination) and things done from duty. Explain the distinctions involved here by offering plenty of examples. Then, using the same examples, explain what conclusions a utilitarian would reach regarding each example and why. Finally, which one of the theories offers a better account of our moral duties? Offer an argument for your view. (Topic) I have a PDF of the textbook I can provide since it is the only source allowed.
