Answer:
150 km/h 
Step-by-step explanation:
because it's then 2 together
 
        
             
        
        
        
A= 4 points
B= 3 points
C= 2 points
D= 1 point
F= 0 points
So you add 2+2+4+4+3+3+3+1
Which equals 22 
Now divide 22 by 8
You get 2.75
So yes with a 2.75 gpa you should pass 8th grade as most schools require nothing less than a 2.0
