Given :
The Ironman endurance race has a 2.4 miles swim. 
Javier can swim 0.5 miles in 20 minutes.
To Find :
How much time in hours it takes to complete the race.
Solution :
Speed of Javier :

Let, time taken to cover 2.4 miles is t .
So, 

Hence, this is the required solution.
 
        
             
        
        
        
Given that Relationship B has a lesser rate than Relationship A and that the graph representing Relationship A is a f<span><span>irst-quadrant graph showing a ray from the origin through the points
(2, 3) and (4, 6) where the horizontal axis label is Time in weeks and the vertical axis
label is Plant growth in inches.</span>
The rate of relationship A is given by the slope of the graph as follows:

To obtain which table could represent Relationship B, we check the slopes of the tables and see which has a lesser slope.
For table A.
Time (weeks)	3	6	8	10
Plant growth (in.)	2.25	4.5	6	7.5

For table B.
Time (weeks)	3	6	8	10
Plant growth (in.)	4.8	9.6	12.8	16
</span><span><span>

</span>
For tabe C.
Time (weeks)	3	4	6	9
Plant growth (in.)	5.4	7.2	10.8	16.2
</span><span>
 
For table D.
Time (weeks)	3	4	6	9
Plant growth (in.)	6.3	8.4	12.6	18.9</span>
<span>

</span>
Therefore, the table that could represent Relationship B is table A.
 
        
        
        
A Because if you do 156 x 20 it equals 3120. It’s A because the volume formula is Length x Width x height, And 156 and 20 were the only numbers given.
        
             
        
        
        
80+20 is ten times 8+2, if you factor out 10 from 80+20 we get 10(8+2)
