Question

A train travels at 100 milers per hour. An equation can be written that compares the time (t) with the distance (d). Define the domain and range​

Answer 1

The domain is t ≥ 0

The range is D ≥ 0

Explanation:

`rate = (distance)/(time)`

D(t) = 100t + d₀

t is the time measured in hours.

d₀ is the initial position of the train.

We can assume the distance they go is not negative so...

The domain is t ≥ 0

The range is D ≥ 0
