Answer:
4.5
  miles
Step-by-step explanation:
Well, he runs 
3
 miles in 
28
 minutes. Also, see that 
42
=
28
⋅
1.5
.
So, his journey would just be running 
1.5
 times, with each time running 
28
 minutes.
So, he runs a total of 
1.5
⋅
3
=
4.5
 miles
 
        
                    
             
        
        
        
Divide by 1000 to convert to kilometers per minute
Then multiply by 60 to convert to kilometers per hour.
Conversion factor is 60/1000  = 0.06  answer
