For a raw material that is used in your plant, daily usage is 60 gallons per day and this amount is deterministic. Lead time from the supplier is normally distributed. The average lead time is 10 days and the standard deviation of it is 2 days. Calculate the standard deviation of demand during lead time.

a.60 times 2 60 times the square root of 10
b.10 times the square root of 2
c.60 times 10
d.60 times the square root of 2
