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? (1 point)
Since they streamed one-fourth of the documentary, they watched one-fourth of the total number of minutes in the documentary, which is 1/4*70 = <<1/4*70=17.5>>17.5 minutes
If 70 minutes have been watched, 17.5 minutes is equal to 70/17.5 = <<70/17.5=4>>4
The documentary has 4 times the minutes of the 17.5 minutes watched, for a total of 17.5*4 = <<17.5*4=70>>70 minutes. Answer: \boxed{70}.
