speed =90km/h=90×5/18=25 m/s
Total distance =350 m
time = 350/25= 14 seconds

Answer:
Explanation:when we solve this types of problem we have to calculate speed and distance perfectly in. Now. Solutions:> as whave length of train 150 m. And bridge length 200m. So as according to question train had to cross bridge w.hen train will cover bridge only when it's whole body covers so therefore lenth of train and length of bridge will be added to find distance so distance will350m and speed of train remain same 90km phthen convert speed into m/sec =90×5/18 =25 m/ sec. So now using formula:> (distance=speed×time) we will have 350m =25× t so t = 350/25=14. Since time taken =14 sec
