 Question 349498: The driving school instructor has asked Lina to stay within 2 miles of the posted speed limit.The current road has a speed limit of 45mi/h.Write a compound inequality to show Lina's acceptable speeds s.Answer by jim_thompson5910(28578)   (Show Source): You can put this solution on YOUR website!She can either drive 2 mph slower than the speed limit (ie at 45-2=43 mph) or 2 mph faster than the speed limit (ie at 45+2=47 mph) So if 's' is her speed limit, then she must travel greater than or equal to 43 mph, which means that . In addition, she must travel at most 47 mph which also means that Combine the two inequalities to get So the compound inequality is If you need more help, email me at jim_thompson5910@hotmail.com Also, feel free to check out my tutoring website Jim
