Answer Posted / ravi
passenger train cross after 4 hrs of starting
but freight train already leaves station before 2 hrs of
passenger train
so the passenger train and freight train speed ratio
passenger train travel hrs : freight train travel hrs = 4:6
passenger train speed in hrs 16km/hr;
then freight train speed = x;
then
4/6 = x/16
then x = 10.66
the freight train speed in hrs = 10.66 km/hr
