Answer:
 (a)  r < 37 or r ≥ 42
Step-by-step explanation:
Translating the given relations to math symbols, we have ...
 "less than 37 minutes"  ⇒  r < 37
 "no less than 42 minutes"  ⇒  r ≥ 42
__
Written as a single statement, this is ...
 r < 37 or r ≥ 42
_____
Additional comment
The solution regions are disjoint, so an "or" statement must be used. The form ...
 37 > r ≥ 42
cannot be used, because it is false that 37 > 42.
