----
&lt;pre&gt;The total trip took 7 1 h of driving time. &lt;/pre&gt;

71 hours seems like too long a time.  There is a space between the two digits.  Not sure if this really was intended as 7 hours or 71 hours.  Decide which is it, and here just a variable will be used for that total drive time, T.  You will decide which to use, from there.

&lt;pre&gt;
                SPEEDS    TIMES     DISTANCE

G to B            50       d/50       d

B to G            75       d/75       d

TOTAL                       T
&lt;/pre&gt;

{{{d/50+d/75=T}}}

-

{{{150(d/50+d/75)=150T}}}

{{{3d+2d=150T}}}

{{{5d=150T}}}

{{{d=30T}}}
My guess is that supposed to be T=7 and then {{{highlight_green(d=210)}}}.


Otherwise, if T=71, then {{{highlight_green(d=2130)}}}.</PRE>
