Answer:
y=11
Step-by-step explanation:
Mean-20.3+12.5+7.9+17.5+15.6+14.1= 87.6
87.6/6=20.1
Median- 7.6+17.5/2= 12.55
7x +2y =-17 ..... Finally, answer
2x + 3y = -5
+
5x -y = -12
---------------------------
7x +2y = -17
Becaus you have 2A and 2b this is what i think it could mean A+A+B+B
Maybe b 60 km/hr for 2 hours
