Question

Расстояние между городами 800 км. Поезд идет из одного города в другой со средней скоростью 70 км/ч. Задайте формулой зависимость расстояния s, которое поезду осталось пройти , от времени движения t.СРОЧНО!!! Заранее спасибо)

Answer 1

T - время движения
s - расстояние
s = 800 - 70t

Answer 2

Formula for Distance Remaining for a Train

To determine the formula for the distance remaining for a train, we can use the formula for distance, speed, and time. The formula is:

Distance (s) = Speed (v) × Time (t)

In this case, the speed of the train is given as 70 km/h, and the time is represented by 't'. The distance remaining for the train can be calculated by subtracting the distance covered from the total distance between the cities.

Let's denote the total distance between the cities as 'd' and the distance covered as 's'. The distance remaining can be calculated as:

Distance Remaining (s) = Total Distance (d) - Distance Covered (s)

Substituting the formula for distance covered, we get:

Distance Remaining (s) = Total Distance (d) - (Speed (v) × Time (t))

In this case, the total distance between the cities is given as 800 km, and the speed of the train is 70 km/h. Therefore, the formula for the distance remaining for the train is:

Distance Remaining (s) = 800 km - (70 km/h × t)

Please note that the formula assumes a constant speed throughout the journey and does not account for factors such as acceleration or deceleration.

I hope this helps! Let me know if you have any further questions.
