               SPEED            TIME          DISTANCE
GOING           91              t             d
RETURN          78              t+1           d

Observe the same distance d for "going" and "return".

Solve this for t, and then evaluate d using .
Basic Travel Rate rule for constant rate R is RT=D, to relate time and distance.
