Answer:
0.39 km west
Explanation:
The position of Runner A is:
x = -5.7 + 8.8 t
The position of Runner B is:
x = 4.2 − 7.6 t
When the positions are equal:
-5.7 + 8.8 t = 4.2 − 7.6 t
16.4 t = 9.9
t = 0.604
Plug into either equation to find the position at this time:
x = -5.7 + 8.8 (0.604)
x = -0.39
The runners are 0.39 km west of the flagpole when they meet.
