Using the features, a piece-wise function is defined, and the graph is sketched at the end of this answer.
A piece-wise function is a function that has <u>multiple definitions</u>, depending on the value of the input.
He starts at 0 feet, and reaches a maximum elevation of 800 feet in 30 minutes, with a steady(linear) increase thus, for the first 30 minutes, the definition is:

For the next 5 minutes, he stops to rest, at the maximum elevation of 800 feet, thus, the definition is:

For the final 20 minutes, he descends 800 meters, at a linear rate, thus:

Using these definitions, the graph is sketched at the end of this answer.
