You can put this solution on YOUR website!
Distance between cities may be d, but not need to be known.

r=%283%2F5%29d%2F%281%2F4%29=highlight_green%283d%2A4%2F%285%29%29

t, how many hours to go distance d.
%283%2A4d%2F5%29t=d just using uniform travel rates rule.

t=d%285%2F%283%2A4%2Ad%29%29
t=5%2F%2812%29

Still t is a fraction of an hour.
t=%285%2F12%29%285%2F5%29
highlight%28t=25%2F60=5%2F12%29, which is 25 minutes.
