Answer:
20/3
Step-by-step explanation:
 
        
                    
             
        
        
        
Average speed =   (distance final - distance initial)/(time final - time initial)
Average speed = (30-0)km /(100 -0)min = 3/10 km/min
3/10 km/min *60 min/1 h = 180/10 km/h= 18 km/h
        
             
        
        
        
Answer:
Step-by-step explanation:                               x - 6
The given equation can be re-written as y = ---------                               
                                                                              -3
Arbitrarily choose x = 0.  Then:
       x - 6         0-6
 y = --------- = ----------- = 2, so (0, 2) is a point on the graph which is also the                               
           -3            -3                                                                  y-intercept
Arbitrarily choose x = 6.  Then y = 0, and (6, 0) is another point on the graph                                    
                                                               which happens to be the x-intercept
arbitrarily choose x = 12.  Then y = (12 - 6) / (-3) = -2.  Then  (12, -2) is            
                                                                                   another point on the
                                                                                   graph.
Plot (12, -2), (6, 0) and (0, 2).  Draw a line through these three points.
 
        
             
        
        
        
Hi!
<h2>
Your answer will be: <em>
180.</em></h2>
Reason being: <em>183-3=180. Also, 180+3=183.</em>
Hope this helps!
