It’s given that during a portion of a flight, a small airplane’s 150 170 cruising speed varied between miles per hour and miles per hour. It’s also given that s represents the cruising speed, in miles per hour, during this portion of the flight. It follows that the airplane’s cruising speed, in miles per hour, 150 $150 170 was at least , which means s , and was at most , which means #170 s . Therefore, the inequality that best represents this situation is 150# #170 s . Choice A is incorrect and may result from conceptual or calculation errors. Choice B is incorrect and may result from conceptual or calculation errors.
