Question 999538
The question type is too common.



<pre>
                   rate          time       distance
WITH WIND          r+w           4.5          3780
AGAINST WIND       r-w           5            3780
</pre>
The data can also be arranged and kept purely in variable symbols.


Basic uniform travel rates RT=D relates rate time and distance.


{{{system((r+w)(4.5)=3780,(r-w)*5=3780)}}}


The arithmetic steps and final computations are not done here and you need to do them.
