Mary, Nadia, Tom, and Nader paced the same distance between two point. The results were: Mary $111\mathrm{.}50$ paces, Nadia $108\mathrm{.}75$ paces, Tom $112\mathrm{.}25$ paces, and Nader $90\mathrm{.}00$ paces. May's pace distance is ${2\mathrm{.}00}^{\text{'}},$ Nadia's is ${2\mathrm{.}05}^{\text{'}},$ Tom's is $1\mathrm{.}95,$ and Nader's is ${2\mathrm{.}20}^{\text{'}}.$ What is your best estimate of the distance?
