Answer:
A.4
Step-by-step explanation:
Because 4/12 is simplified to 1/3 and 2/4 would be simplified to 1/2. 1/2 > 1/4
 
        
             
        
        
        
Answer:
Train A is faster by a factor of 1.01
Step-by-step explanation:
Given:
Train A:
Distance = 175 Miles
Time = 4 Hours
Train B:
y=43.5x
To Find:
which train travels at a faster rate in by what factor  =?
Solution:
The speed of the train A = 
The speed of train A  =
The speed of train A = 43.75 miles per hour
Speed of the train B is the slope of the given line
The standard equation of the slope of the line is 
y = mx+b
where m is the slope
and we are given with
y = 43.5x
So comparing with the standard equation 
m = 43.5
Hence the speed of train B is  43.5  miles per hours
Train A travels faster


rate  =1.01
 
        
             
        
        
        
Y = 5 x 3 + 8
y = 15 + 8 
y = 23
