Question

Alice spent 36 minutes listening to 9 songs. If each song takes the same amount of time, how long would it take Alice to listen to 20 songs?

Answer 1

Each song lasts 4 minutes, as 36/9 equals 4. If Alice listens to 20 more songs, 4 minutes each, then it’ll take her 80 minutes (or 1hr, 20 minutes) because 20x4=80.

Answer 2

First divide 36 by 9 and get 4, now you have your number of minutes per song. Now multiply that by 20 to get 80 minutes for 20 songs.

In short: 80 minutes for 20 songs.
