The best way to see what is happening in both situations is to create a table showing the new elevation after each minute.
Please see the attached picture for the work.
After five minutes, both balloons will be at the same height.
The width would be 16
4x22=88
1408-88= 1320
22x16x4= 1408
You take 80 words per minute × how many minutes which is 30 which will equal 2400.
