Need a human answer!!

An airplane flies at a speed of $359$ mph at an altitude of $10,000ft.$ If the boundary layers on the wing surfaces behave as those on a flat plate, $($a$)$ estimate the extent of laminar boundary layer flow along the wing. Assume a transitional Reynolds number of $R{e}_{xcr}=5{10}^5.$ If the airplane maintains its $359-$mph speed but descends to sea$-$level elevation, $($b$)$ estimate the extent of the laminar boundary layer flow. $($c$)$ Will the portion of the wing covered by a laminar boundary layer increase or decrease compard with its value at $10,000$ ft$?$

$($a$)x_{cr}=$ ft

$($b$)x_{cr}=$

$($c$)$
