Question 748396
Letting r = average speed for the trip,


________________rate___________time__________distance
Actual___________r______________6____________{{{r*6}}}
Fictional________r+10___________5____________{{{(r+10)*5}}}


Immediately filled information were rate and time.  Calculated expressions were the distance, giving two different expressions.  The distance for "Actual" and for "Fictional" are equal.  That is the same distance done at different rates.


{{{6r=5(r+10)}}}
{{{6r=5r+50}}}
{{{highlight(r=50)}}}
