see image explanation attached
Answer:
D
Step-by-step explanation:
so by process of elimination it can’t be A as it is a 7hr journey
B is also incorrect as she travels 50mph not an additional 50miles per hour (50m in hour one then 100m in hour 2 )
C is also incorrect as she travels 50 miles in ann hour not in 6
D is correct as she has travelled 200 miles
(68 + 82 + 87 + 89 + x) / 5 > = 80
(326 + x) / 5 > = 80
326 + x > = 80 * 5
326 + x > = 400
x > = 400 - 326
x > = 74.......u would have to make at least a 74 to earn a B
-3 x + 1 > y
1/2x -1 (less than or equal to) y
