Francisco is right you always answer with si And the question 2 and 3 will be better ¿A que hora escucha ud. música? Without the “la” R/ yo escucho música a las dos. ¿Viajas mucho?

"¿A qué hora (Usted) escucha música?" "¿Viajas mucho?" These are the best way you can write them. The first one is correct but sounds a little bit strange for native speakers. The second one IS WRONG, because "Viajas" is crearly a verb in 2nd person, is unnecesary to write the word "tú"

Thank you!

For me they are ok. But would be great whether for the first and third questions you start the answer with " Sí". When you say "Sí" at the beginning you are affirming. "Sí, yo canto en la ducha" "Sí, yo viajo mucho". :) Keep learning. Good job.
