If you travel for one hour, how far have you gone    120 km.
If you travel for another hour how far do you additionally go.    120 km      total trip so far. 240 km.
If you travel for another hour how far do you additionally go.    120 km      total trip so far. 360 km.

you now need a fraction of an hour to complete the trip.   That fraction is
(additional distance needed/speed you are going)      40/120

Of course you could use shah's note to start with.
