Yes. Just use either of the two Haversine function implementations to calculate the (straight 
line) distance and divide by a typical walking speed.

Yes;  you want to reach the Rottnest Ferry as quickly as possible, prior to 15:30.
Though, of course, trains will not overtake each other on the Fremantle Line,  so it's only the 
walking time that may be a factor.
