In my work I used t=trains and m=minutes:
30+30= 60m/2t
<span>30+30= 60m/2t
</span><span>30+30= 60m/2t
</span><span>30+30= 60m/2t
</span><span>30+30= 60m/2t
</span><span>30+30= 60m/2t
</span><span>30+30= 60m/2t
</span><span>30+30= 60m/2t
</span><span>30+30= 60m/2t
</span><span>30+30= 60m/2t
</span><span>30+30= 60m/2t
</span><span>30+30= 60m/2t
Total= 720m/24t
1:30+1:30+1:30+1:30+1:30+1:30+1:30+1:30+1:30+1:30+1:30+1:30= 4 o' clock
Total= 372m/12t
24t+12t= 36t
The answer is:
36 trains in total</span>
        
             
        
        
        
Answer:
12
Step-by-step explanation:


When F = 18; d = 2


Cross multiply;
18 x 4 = K
72 = K
There the equation connecting F and  is
 is

Now, Find F when d = 6
All you do is to substitute d = 6 in to 

Therefore;
F = 12
Please mark me brainiest if correct.
 
        
             
        
        
        
Answer:
x=2
Step-by-step explanation:
3(5x+2)=8x+20
Distribute the 3
15x +6 = 8x+20
Subtract 8x from each side
15x-8x +6 = 8x-8x+20
7x+6 = 20
Subtract 6 from each side
7x+6-6=20-6
7x=14
Divide each side by 7
7x/7 = 14/7
x=2
