Answer 2

Answer : Option D is correct .

Step-by-step explanation:

Since we have given that

he descended 300 meters in 5 hours i.e.

We should use negative sign with 300 meters as he descended .

And the answer must be in negative .

But in option 'd ' there are two negative signs which make it positive , which can't be its answer as it will denying the statement that ' he descended 300 meters in 5 hours'.

So, option D is not equivalent to Howard's average change in location per hour at all.
