How long will it take to get to the museum?

W:  Hey,  taxi!  Ah,  great. Thanks for stopping.
M:  Where to?
W:   Well,   I’m going to the National Museum of Art. How long does it take to get there?
M:  Well,  that all depends on the traffic,  but it shouldn’t take more than 30 minutes.
W:  Oh,  by the way,  do you know what time the museum closes?
M:   Well,   I would guess around six o’clock. Is this your first time to the city?
W:  Yeah. Do you know any good restaurants downtown that offer meals at a reasonable price?
M: Umm, well, the Mexican restaurant, La Fajita. It’s not as inexpensive as other places I know,  but the service is better.
