In a double$-$slit experiment using monochromatic light, the slits have a separation distance of $28\mathrm{.}1m.$ When $645-nm$ wavelength light is used, the distance to the $4-$order maximum $($from the central maximum$)$ is $11\mathrm{.}6$ cm $.$ What is the distance to between the slits and the screen?

Enter your answer in units of meters. For example, if your calculation produces a value of $1\mathrm{.}23$ m $,$ enter your answer as $1\mathrm{.}23.$
