One car 40 miles /gallon
 other car 30 miles/gallon
 ..
 Total miles = 165 
 gas used = 45 gallons
 ...
 let first car drive x miles
 second car drive y miles
 ..
 x/40 + y/30 = 45
 (30x+40y)/30*40 = 45
 30x+40y = 45*40*30
 30x+40y=54,000
        
                    
             
        
        
        
Answer:
1/36
Step-by-step explanation:
To get a sum of 2, both dice must roll a 1.
The probability of a 1 on the first die is 1/6.
The probability of a 1 on the second die is 1/6.
Therefore, the probability of rolling both 1s is:
P = 1/6 × 1/6 = 1/36
