To solve this problem, we need to determine the time it takes for the two trains to meet. Once we know the meeting time, we can calculate the distance the bird has flown.

Let’s start by finding the meeting time of the trains. Since they are moving towards each other, we can use the concept of relative speed.

The relative speed of the two trains is the sum of their individual speeds: Relative speed = Speed of train A + Speed of train B

Relative speed = 60 km/h + 90 km/h Relative speed = 150 km/h

Now, we can use the formula: Time = Distance / Speed

Time = 450 km / 150 km/h Time = 3 hours

Therefore, it will take 3 hours for the two trains to meet.

Now, let’s calculate the distance the bird will have flown during this time.

Since the bird is flying back and forth between the two trains, we can consider the bird’s speed relative to the trains. The relative speed of the bird with respect to the trains is the difference between their speeds: Relative speed = Speed of bird – Speed of train A (or train B)

Relative speed = 120 km/h – 60 km/h (since the bird is flying towards the train)

Relative speed = 60 km/h

Now, we can use the formula: Distance = Speed x Time

Distance = 60 km/h x 3 hours Distance = 180 km

Therefore, the bird will have flown a distance of 180 kilometers when the trains meet.

Note: The bird’s speed and direction are such that it can easily maintain the same distance from each train as they move towards each other.

Technology has become an integral part of our lives, offering convenience and connectivity. However, it is essential to acknowledge the negative impact it has on today’s generation. While technology brings numerous benefits, its excessive use and misuse can have detrimental effects on physical health, mental well-being, and social interactions.

1. Physical Health: The rise of technology has contributed to sedentary lifestyles among today’s generation. Excessive screen time spent on smartphones, tablets, and computers has led to a decline in physical activity, resulting in various health issues such as obesity, poor posture, and weakened eyesight. Furthermore, prolonged use of handheld devices often leads to repetitive strain injuries like text neck and carpal tunnel syndrome.

2. Mental Well-being: Technology overexposure has a significant impact on the mental well-being of today’s generation. Constant exposure to social media platforms creates a culture of comparison, leading to feelings of inadequacy, low self-esteem, and even depression. The addictive nature of technology can also disrupt sleep patterns, impair concentration, and increase anxiety levels. Additionally, the prevalence of cyberbullying and online harassment can have severe emotional consequences, causing stress and social isolation.

3. Social Interactions: While technology has enhanced communication, it has also affected face-to-face interactions. Excessive use of digital devices has resulted in reduced real-world social connections. Many young individuals find it challenging to develop effective communication skills and build meaningful relationships. The constant presence of technology during social gatherings often distracts individuals from fully engaging with others, hindering genuine human connections.

Conclusion : Although technology brings undeniable benefits, it is crucial to recognize the negative impact it has on today’s generation. By being mindful of technology usage and promoting a balanced lifestyle, we can mitigate the adverse effects on physical health, mental well-being, and social interactions. Encouraging outdoor activities, fostering healthy online habits, and promoting face-to-face interactions can help create a healthier and more balanced relationship with technology.
