You can put this solution on YOUR website! Trip going was at a faster speed, R. Trip back was at lower speed r. Variables also shown as assigned assumed.
SPEED TIME DISTANCE
GOING R x d
RETURN r y d
Basic constant travel rate rule is RT=D relating speed, time, distance.
R=unknownSpeedGoing
d=unknownDistanceOneWay
r=32
x=3
y=4
 ------because you could simply equate two expressions for d.
