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

Let 'x' represent the time needed to record 9 songs.
Since the rate is the same we have:
4/3 = 9/x
9/x = 4/3

x = 6.75 hr
x = 6 hr 0.75*60 min
x = 6 hr 45 min
