A
X > Y

B
X < Y

C
X ≥ Y

D
X ≤ Y

Solution

x² + 26x + 168 = 0

x = -12, -14

y² + 23y + 132 = 0

y = -12, -11

A runs 3 2/3 times as fast as B. If A gives B a start of 80 m. How far must the winning post be from the starting point of A so that A and B reach it at the same time?

A
200 m

B
110 m
