the relative speed of 2 car w.r.t. 1 is (60-48) km/hr = 18 km/hr = 5m/s
it has to cover a distance of 5 m
hence time required is 1 s
now it also has to get through its length of 5 m
hence it would take 1s more
so total time taken is 2 s
in 2 s 2nd car cover a distance of 60*5*2/18= 10*10/3 = 100/3 = 33 .33 m
hence my ans is 33.33 metre
