Did this on EDGE!
It is 70
i cant explain it right now i have work to do so sorry:)
I got 6 for my answer, but I'm not 100% sure if I'm right.
6(2x-11)+15=21
12x-66+15=21
12x-51=21
+51 +51
12x=72
----- ----
12 12
x=6
40 tables, 4 tables per 12 minutes so 40/4*12 which would be 120 minutes.
Hope this helps!
