According to the 85% cumulative average-time learning curve, the time for n-th unit can be calculated using the following formula:

Tn = T1 * n^log(0.85)

where, 
T1 = time for the first unit (300 minutes)
n = serial number of the unit

For the second setup on the new machine, n = 2

T2 = 300 * 2^log(0.85) 
= 210.08 minutes (rounded off to nearest minute)

Therefore, the expected time for the second setup on the new machine is 210 minutes.
