How to find the estimated mean of a sampling distribution?

The mean time to run a race by all of the runners is 60.75 mins and the standard deviation is 4.5 minutes. What is the estimated mean for a sampling distribution of the sample if the sample size is is 30? Also does anyone know what formula to use and if possible can you outline the steps to follow so.
