--------------------
A man travels 180km from his farm to town, In a loaded truck.on return journey he is able to travel 30km\h faster having unloaded his truck.he saves 1hour on return journey by travelling faster. 


Table: 
Under journey ke:from farm 2 town 
From town to farm
.
distance,: 180km from farm to town  
Speed? 
Time: 180 over x 
From town to farm: distance?? 
Speed:x + 30
Time??
-------------------

<pre>
                    SPEED           TIME         DISTANCE

FARM to TOWN         x              180/x           180

TOWN to FARM        x+30           180/(x+30)       180

Difference                           1
</pre>

Find the speed of truck fully loaded when going from farm to town using {{{180/x-180/(x+30)=1}}} and solve for x.

You can then use this to find the two times.
