A band went to a recording studio and recorded 4 songs in 3 hours. How many hours would it take the band to record 9 songs if they record at the same rate?

6 hours and 45 minutes

Step-by-step explanation:

if you divide 3 hours by four songs you deduce that it take 45 minutes to record one song.

8 is double 4 so it will take 3more hours plus the 45 minutes for the ninth song.

3+3+.45 = 6.45

7 1/2 hours I believe is the correct answer. Hope it works!
