$2\mathrm{.}5\mathrm{.}2$ Aneroid barometers can be used to measure changes in altitude. If a barometer reads $30\mathrm{.}1$ in$.$ Hg at one elevation, what has been the change in altitude in meters when the barometer reading is $28\mathrm{.}3$ in$.$ Hg $?$ Assume a standard atmosphere and that Eq$.2\mathrm{.}12$ is applicable over the range of altitudes of interest.
