length of the train =210 m
time taken to cross the 90 m tunnel =12 second
the speed of the train =distance /time
=90m + 210 m/0.2 minute
=300m/ 0.2minute
=1500 m/minute
=90 km/h
time taken to cross the 90 m tunnel =12 second
the speed of the train =distance /time
=90m + 210 m/0.2 minute
=300m/ 0.2minute
=1500 m/minute
=90 km/h

Answer:
Therefore, the total distance covered by the train = 210 + 90 = 300 m. Time taken by the train to cover the total distance = 12s. Obtained speed is in meter/second, we have to convert it into kilometers per hour. Therefore, the speed of the train is 90km/hr.
