```										Dear Jaya,v2 - u2= 2 a S   -------- eq.1v=final velocityu=initial velocitya=accelerartion(in this case retardation)S=distance travelledOn solving;by converting given speeds which are in km/hr to m/s by multiplying the speeds by 5/18;we get, accelaration=-2 m/s or -0.555km/hr.(- sign indicates retardation)v = u + a t -------eq.2t=time taken.time taken = 10 sec on solving.Approve if my answer helped you.
