Question

Поезд, дви­га­ясь рав­но­мер­но со ско­ро­стью 150 км/ч, про­ез­жа­ет мимо стол­ба за 6 се­кунд. Най­ди­те длину по­ез­да в мет­рах.

Answer 1

Обязательно приводи данные к одному наименованию,т.е. км/ч выражай в м/с.

Answer 2

Calculation of the Length of the Train

To find the length of the train, we need to use the formula:

Length = Speed × Time

Given that the train is moving at a constant speed of 150 km/h and passes a pole in 6 seconds, we can convert the speed to meters per second and the time to seconds for consistency.

Converting the speed: - 150 km/h = 150,000 meters/3600 seconds = 41.67 meters/second.

Converting the time: - 6 seconds = 6 seconds.

Now we can calculate the length of the train using the formula:

Length = Speed × Time = 41.67 meters/second × 6 seconds = 250 meters.

Therefore, the length of the train is 250 meters.
