Wednesday, 25 January, 9:50 pm, Dear Diary, Today was a transformative day as I visited a blind school for our social service and moral education class. The resilience and determination of the students left an indelible mark on my heart. Witnessing their unwavering spirit to learn and excel despite the challenges was truly inspiring. The teachers' dedication was commendable, fostering an environment of warmth and encouragement. Interacting with the students, I realized the power of empathy and the importance of inclusivity. Their optimism in the face of adversity taught me profound lessons about gratitude and resilience. I am motivated to contribute more to society and spread awareness about the abilities and potential of differently-abled individuals. This experience has enriched my understanding of compassion and reinforced the significance of kindness in our lives. Gratefully, Krishna

Himani Kumari 9 months, 4 weeks ago

Step 1, Given data Length of the train = 200 m Length of the bridge = 400 m Velocity of the train = 36 km/h = 10 m/s Step 2, Find the time taken For the complete crossing of the bridge, the train has to travel a total distance equal to 400 m + 200 m = 600 m We know, Time taken = total distance/velocity Putting all the values Time= 600/10= 60 sec Hence the time taken by train to cross the bridge is 60 sec or 1 min.
