Carly Brittany and Lauren streamed one fourth of an eight episode documentary. If 70 minutes of the documentary have been watched how many minutes are in the documentary
Since one fourth of the documentary has been watched and there are 8 episodes in total, then one episode is equal to 70 minutes / (1/4) = 280 minutes.
Therefore, the total duration of the documentary is 8 episodes x 280 minutes = 2240 minutes.
