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?

Answer 1

What we know about this situation that either she will take less than 37 minutes:

r<37

or she will take more than 42 minutes

r>42

so it means that she cannot take between 37 and 42 minutes.

The best way to write it is:
37>r v r>42

where "v" means "or" in mathematical notation

Answer 2

Answer:

Step-by-step explanation:

37> r > 42
