Answer:
Step-by-step explanation:
rate = d / t
rate = 192 / 3
rate = 64 miles / hour
Now you want to know how long it can take to get 448 miles
d = r * t
t = d / r
t = 448/64
t = 7 hours.
You could actually do it using proportions.
192/3 = 448/x                   Cross multiply
192*x = 448*3
192*x = 1344                    Divide by 192
x = 1344/192
x = 7
Do this the way you feel is the best way.
 
        
                    
             
        
        
        
Equation t= $7 times w 
$7 times 4 = $28 
        
             
        
        
        
Would have to be C due to all the other numbers not adding up to be a right angle
