The high school dance team is learning a new routine to a song that lasts 3 minutes and 41 seconds, or 221 seconds total. Yesterday, they covered the first 45 seconds of the song at practice. They learn an average of 22 seconds of the dance in an hour. Let h represent the time, in hours, it will take the team to learn the entire dance. Which equation represents this situation, and how long will it take?

A. 221 = 22h; 11 hours

B. 221 = 22h - 45; 12 hours

C. 221 = 22h + 45; 8 hours

D. 221 = 45h + 22; 5 hours
