152
Step-by-step explanation:
45 seconds = 45/60 minutes = 3/4 minutes . Number of copies = 4*32 + (3/4)*32 = 128 + 24 = 152
 
        
             
        
        
        
Well, I don't know Mark's reasoning, but the square root of 2 is not a rational number. A rational number is a number that can be represented by a fraction - its decimal form must either be finite (have an end) or repeat (for example, 1/3 or .3333333...). The square root of 2 is infinite and cannot be written as a fraction, so it's not rational.
 
        
             
        
        
        
Here, You need to calculate the slope of the graph by taking any two random points, as follows:
(x₁,y₁) = (0,0) & (x₂,y₂) = (1,55)
Now, we know, 
y₂-y₁ = m(x₂-x₁)
55-0 = m(1-0)
m = 55/1
m = 55
Here m represents the slope of graph which is nothing but rate of change of distance.
In short, option A will be your answer.
Hope this helps!
        
                    
             
        
        
        
We can use proportion to solve it


Our x is equal to =

min
Its our result
