A function I could think of is the distance traveled by our car running at a constant speed of 20 mph towards our school which is 5 miles from home.

The function name is D (t)

D (t) = 20t

wher t is the time traveled in hours

The maximum distance traveled is

5 = 20t

t = 0.25 hours

The domain is 0 ≤ t ≤ 0.25

The range is 0 ≤ D (t) ≤ 5
