d(t) = 40 + 85(t - 1) if 1 < t <= 4
= 295 + 60(t - 4) if 4 < t <= 6

Range:
The range is the set of possible values for the distance function given the zero to six-hour domain. The upper limit of the range is the total distance traveled.
The one glaringly idiotic assumption is that he thinks he is going to go 85 miles per hour for 3 hours on a California Interstate Highway without having to, at best, wait 20 minutes while the CHP writes him a citation, or at worst having to spend the night in a local jail cell. Maybe he is an entitled millennial and thinks that speed limits are damaging to his self-esteem.
