It is the Pareto Graph. It is a bar graph in which bars are arranged in frequency order. Pareto graph is the combination of bar and line graph that displays the data in a descending order.  It has an 80/20 rule.
        
             
        
        
        
We have been given that the upstream speed is  and the down stream speed is
 and the down stream speed is  .
. 
Let the fisherman traveled a distance of x miles. 
The total time of the trip is 6 hours. 
Relations between speed (s), time (t) and distance (d) is 
Hence, 
Time upstream +  time downstream = 6 

lcm = 10 

=> 
Cross multiplying, 
x = 20 miles .. Answer.
