Given variables assigned:
system%28d=175%2Cu=3.5%2Cv=4%29

_________________speed__________time_________distance
GO______________________________u_____________d
BACK____________________________v_____________d
Total__________________________u+v___________2d

The average "rate of travel" is asked, but the two rates for going and returning are not needed.

Average rate, highlight%28%282d%29%2F%28u%2Bv%29%29
