Consider a $55$ $kg$ woman who has a total foot imprint area of $440$ $cm^2$. She wishes to walk on the snow, but the snow cannot withstand pressures greater than $0.4$ $kPa$. Determine the minimum size of the snowshoes needed (imprint area per shoe, in $m^2$) to enable her to walk on the snow without sinking. Imprint Area/Shoe = $m^2$
