Imagine that you take a road trip from A to D, but you have to do it in segments. Let’s say the distance from A to B is 145 miles; from B to C is 160 miles, and C to D is 115 miles. It takes you 6 hours to drive from A to D. What was your average speed (in miles per hour) during your trip from A to D? (Hint: How many miles did you drive from A to D? Then divide the total miles by the number of hours).

Three consecutive even numbers have a sum between 84 and 96. a. write an inequality to find the three numbers. let n represent the smallest even number. b. solve the inequality. a. 84 ≤ n + (n + 2) + (n + 4) ≤ 96 b. 78 ≤ n ≤ 90 a. 84 < n + (n + 2) + (n + 4) < 96 b. 26 < n < 30 a. 84 < n + (n + 1) + (n + 2) < 96 b. 27 < n < 31 a. n + (n + 2) + (n + 4) < –84 or n + (n + 2) + (n + 4) > 96 b. n < –30 or n > 31
