The total trip took 7 1 h of driving time.

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.
                SPEEDS    TIMES     DISTANCE

G to B            50       d/50       d

B to G            75       d/75       d

TOTAL                       T

d%2F50%2Bd%2F75=T
-
150%28d%2F50%2Bd%2F75%29=150T
3d%2B2d=150T
5d=150T
d=30T
My guess is that supposed to be T=7 and then highlight_green%28d=210%29.

Otherwise, if T=71, then highlight_green%28d=2130%29.
