Two$-$workstation line with variation

WORKSTATION $1$

Processing time $=$ U$(0\mathrm{.}5,1\mathrm{.}5)$

WORKSTATION $2$

Processing time $=$ U$(0\mathrm{.}5,1\mathrm{.}5)$

Now suppose the processing time for each workstation averages one minute, but varies along a uniform distribution ranging from $0\mathrm{.}5$ to $1\mathrm{.}5$ minutes $($represented by U$(0\mathrm{.}5,1\mathrm{.}5)).$

$4.$ Qualitatively, how do you expect your answers to the three previous questions to change for this process?
