Answer:
13.31 minutes  
Step-by-step explanation:
800 in 30min 
400 in 15 min 
26 passengers in an min
346/26
13.31 minutes  
 
        
             
        
        
        
Since 300 is 100%, you treat it as such.
300/(100/70) = 210 (rounded)
You do a similar thing for 600
1/4 of 100 is 25 
100/25 = 4
600 / 4 = 150
70% of 300 is more.
