Amsar ita ce: 20. <eng> First find the total number of braids among all the dancers: 8 dancers * 5 braids / dancer = 40 braids. Then multiply by that the time in seconds per braid to find the total time in seconds: 40 braids * 30 seconds / braid = 1200 seconds. Then divide the time in seconds by the number of seconds per minute to find the time in minutes: 1200 seconds / 60 seconds / minute = 20 minutes.
