Answer:
Speed = distance travelled / time taken
Here, distance travelled = length of the train + length of the platform
Because your train will be considered crossed the platform only after its full length has crossed the platform
Therefore, distance = 160+160 = 320m
Time = 16s
Speed = distance / time
Speed = 320/16 = 20m/sec
Now, convert it to km/h
Use the basic concept , 1m = 1/1000km
And 1sec = 1/3600 hr (1hr = 60min = 60*60sec)
Therefore, our speed = (20*3600)/1000 = 72km/hr
