It depends on what mode of transportation that you are taking.
You can use the jeepneys, the bus or taxis. I don?t know the exact fare as this will depend on your starting point (Quezon City is a huge city) and where your ending point in Cavite is.
You mustn?t forget Bacoor is also a big place.
The starting fare for a taxi is 30php at flag down and from there onwards it?s 2.50php (approximately every 2 minutes).
