Answer:
2.72 km 
Explanation:
(12.33 km)/ 1 hr * (1 hr)/ 60 min 
0.2055 km/ min
distance=rate * time (assuming v is constant, 
a=0)
(0.2055 km/ min)*(13.22 min)
2.72 km OR 2716.71 m 
 
        
                    
             
        
        
        
Answer:
b. 3 times
Explanation:
Lets take
Coefficient for ordinary glass = α₁
Coefficient for pyrex glass = α₂
  Given that α₁ = 3 α₂
Initial length of both glasses are equal = L
Change in the temperature is also same .= ΔT
We know that change in the length  given as
ΔL =  L α ΔT
Therefore


ΔL₁ = 3ΔL₂
Therefore change in the length of original glass is three time of pyrex glass.
b. 3 times
 
        
             
        
        
        
I'm not sure I completely understand the expression you want evaluated.
It looks like a fraction with the same exact thing in both the numerator and the denominator. A fraction like that always boils down to ' 1 '.
 
        
                    
             
        
        
        
Answer: I think it would be 72 because 12x3=36 and then all the chick have 2 feet each so you would multiply t but 2 and that would be 72
