Question 1053493
This is a certain kind of constant travel rates problem that is asked OFTEN as an exercise.  OFTEN!!!  You may want to solve this generally, and that is what I will <s>try</s> start to do here.


<pre>
                  SPEED           TIME          DISTANCE

AGAINSTWIND       r-50            t+1            375

WITHWIND          r+50            t              375
</pre>
Some two variables are implied in the data table there.


Instead of using those other given values, the  tabulated data can be done in variables only, and again you can figure what is being assigned:

<pre>
                  SPEED           TIME          DISTANCE

AGAINSTWIND       r-w              t+h            d

WITHWIND          r+w              t              d
</pre>
The UNKNOWN variables are r and t.  All of the units are miles,hours,milesPerHour.


You already understand and can use {{{RT=D}}};


{{{system((r-w)(t+h)=d,(r+w)t=d)}}}
CAN YOU SOLVE THIS SYSTEM FOR t AND FOR r  ?
