Question 20 Correct 8.75 points out of 8.75 Solve the problem. a. Assume that traffic flows at a rate of 215 vehicles per hour on the stretch of road between intersections D and A. Find the flow rates x , x , and b. If traffic flows at a rate of between 195 and 270 vehicles per hour inclusive between intersections D and A, find the flow rates x , x , and x Select one: 1 2 3 1 2 3 x . . a. a. x = 55, x = 205, and x = 165; b. 35 ≤ x ≤ 110, 185 ≤ x ≤ 260, and 145 ≤ x b. a. x = 55, x = 205, and x = 165; b. 40 ≤ x ≤ 115, 180 ≤ x ≤ 255, and 155 ≤ x ≤ 230 c. a. x = 65, x = 195, and x = 170; b. 40 ≤ x ≤ 115, 180 ≤ x ≤ 255, and 155 ≤ d. a. x = 65, x = 195, and x = 170; b. 35 ≤ x ≤ 110, 185 ≤ x ≤ 260, and 145 ≤ x ≤ 220 The correct answer is: a. x = 55, x = 205, and x = 165; b. 35 ≤ x ≤ 110, 185 ≤ x ≤ 260, and 145 ≤ x 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3 1 2 3 ≤ 220 x ≤ 230 ≤ 220
