Estimating travel time

¿Cuánto tarda en llegar?

KWAN-toh TAR-dah en yeh-GAR — How long does it take to get there?

"¿Cuánto tarda en llegar al aeropuerto desde aquí?"
How long does it take to get to the airport from here?

"Tardar" is the verb Spanish uses for duration of a trip or task — a false-friend trap in reverse, since it looks like "to be tardy" but really just means "to take (time)."

"A phrase I use constantly, since I am genuinely terrible at estimating how long anything takes."— Graciela
