Luis is tаking his girlfriend, Rоsа, tо а resоrt town neither one of them has visited. Luis wants to make a good impression on Rosa, so he spends the week before the trip reading about fun places to go while they are there. He also memorizes a map of the small resort town, so he can lead her around without bothering to ask for directions. When they arrive, they first visit a botanical garden. When Rosa says, "Where to next?" Luis conjures a mental image of the map and says, "art museum." Let's assume the garden was six inches due south on the map and that it took Luis four seconds to scan the map image between the two. After they visit the museum, Luis takes Rosa to a fancy restaurant. On the map, the restaurant was three inches northwest of the museum, so it is most likely that when Luis scanned the image to find the restaurant, the scan took approximately how many seconds?
