Question

ПОМОГИТЕ ПОЖАЛУЙСТА!!!!Пассажир поезда, идущего со скоростью 50 км/ч, заметил, что встречный поезд шел мимо него в течении 10 секунд. Определите длину встречного поезда, если его скорость-58 км/ч.

Answer 1

50+58=108 км/ч-скорость с которой встречный поезд проезжал мимо пассажира
2)108 км/ч=108 х1000 : 3600(м/с)= 30 м/с
3) 30 х10 = 300 м -длина встречного поезда

Answer 2

Calculation of the Length of the Oncoming Train

To determine the length of the oncoming train, we can use the information provided:

- The passenger's train is traveling at a speed of 50 km/h. - The oncoming train is passing by the passenger's train for a duration of 10 seconds. - The speed of the oncoming train is 58 km/h.

To calculate the length of the oncoming train, we can use the formula:

Length = (Relative Speed × Time) / Speed of the Oncoming Train

Let's substitute the values into the formula:

Relative Speed = Speed of the Passenger's Train + Speed of the Oncoming Train = 50 km/h + 58 km/h = 108 km/h

Time = 10 seconds

Speed of the Oncoming Train = 58 km/h

Length = (108 km/h × 10 seconds) / 58 km/h

Now, let's calculate the length of the oncoming train:

Length = (108 km/h × 10 seconds) / 58 km/h = 1080 km/ h * s / 58 km/h ≈ 18.62 meters

Therefore, the length of the oncoming train is approximately 18.62 meters.

Please note that the above calculation assumes that the length of the passenger's train is negligible compared to the length of the oncoming train.
