Seems to me like a boring question - you poor thing but I guess having done it, it will be some good reference material. Well for a start, physical journeys is too broad a topic area for you to say everything. The only thing that matters for you to say is stuff that your support material can add too. I'd start with waxing lyrical a bit about the power of the physical journey to transform lives blah. Then a general sweep of the subject that your stuff will enlarge upon - so, physical journeys can take many forms, they can be taken by heros or commonplace people with ordinary lives, they are for the brave but esspecially for the fearful - or some crap you could even end with an emphatic statement like - but those which offer the most life-enhancing potential are always - blah, ie you say something which your texts all contain - hopefully they are linked in some way.
Then it really is pretty easy - you take em one by one and say how the text type, the structure and one or two major features highlight certain aspects of your thesis above.
Your book - I don't know but maybe it's in the third person narrative which allows us intimate insight into the characters thoughts and feelings then give a quote.
Your 60 minutes stuff - maybe it's highly emotive? Look at how it's edited, do you get bits in the middle that retell earlier points? is there emotive music? Close ups? How do these things bring to life aspects of the journey (obstacles, triumphs, isolation, finding previously unknown strengths?
Your shor story - again I don't know obviously but a short story is condensed, often it can be more risk taking in it's form that couldn't be sustained over a whole novel, it usually jumps right in and often has the character reflect on an earlier time. God I'm going on
good luck
