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

r < 37 or r ≥ 42

Explanation: "Less than 37 minutes" gives r < 37. "No less than 42 minutes" means at least 42, so r ≥ 42. Combined: r < 37 or r ≥ 42.
