working simultaneously and independently at an identical constant rate , 5 machines of a certain type can produce a total of x units of product p in 4 days . how many of these machines , working simultaneously and independently at this constant rate , can produce a total of 2 x units of product p in 2 days ?
n0 = 5.0
n1 = 4.0
n2 = 2.0
n3 = 2.0
t0 = n1 / n3
t1 = n0 * n2
answer = t0 * t1
