Question

If a bus driver leaves her first stop by 7:00 a.m., her route will take less than 37 minutes. If she leaves after 7:00 a.m., she estimates that the same route will take no less than 42 minutes. Which inequality represents the time it takes to drive the route, r?

r < 37 or r ≥ 42
r < 37 or r > 42
37 < r ≥ 42
37 > r ≥ 42

Answer 1

i believe the third one so this 37 < r ≥ 42 Step-by-step explanation:

Answer 2

(a) r < 37 or r ≥ 42

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.
