If the sewing machines are independent of each other, then the number of shirts is proportional to number of sewing machines x time. So,

5 : 5 x 5, or:

5 shirts/[5 machines x 5 minutes] = 1 shirt per 1 machine in 5 minutes.

5 /[5 x 5] = 100/[100 x M], and

M = 5 minutes - so takes 5 minutes for 100 sewing machines to make 100 shirts.
