(-∞,∞)
Step-by-step explanation:
This function is a line, with a positive slope, that never ends, so the range is negative infinity to positive infinity (non-inclusive).
Their distance differs by 15 miles for each hour of travel time. Thus, the travel time of interest is
.. (180 -144) miles/(15 miles/hour) = 2.4 hour
The red car's speed is 180 mi/(2.4 h) = 75 mi/h.
The blue car's speed is 144 mi/(2.4 h) = 60 mi/h.
