Answer:

The length of the bridge is 300m but the length of the train is 100m so the distance covered by the train in order to completely cross thr bridge is 300 +100 =400m

Now we know speed= distance/time

So,speed= 400/45~8.88m/s

If you want the answer in km/hr then multiply 8.88 by 3600/100

Which will be 31.968km/hr~32km/hr
