Atrain travels at 100 miles per hour. an equation can be written that compares the time (t) with the distance (d). define the domain and range.

If t is time and d is distance, and the train travels at 100 mph.

Our equation will look like:

d = 100t, where "t" is in hours

The domain is all possible values of t.  We will assume that negative time isn't a possible thing in this scenario, so the domain of t:

t ≥ 0

The range of this equation is all possible values for d. Since "t" cannot be less than zero, our range:

d ≥ 0

answer

yeah i know the problem you need. i am taking it right now. the answer is step 3
