Question

Поезд экспрес шёл 3 часа со скоростью 180 км.час.потом он увеличил скорость на 85 км.ч и через час прибыл на конечную станцию.Какой путь прошёл поезд?

Answer 1

1)180*3=540 км
2)(180+85)*1=265 км
3)540+265=805 км

Answer 2

Calculation of the Distance Traveled by the Train

To calculate the distance traveled by the train, we need to consider the initial speed, the increased speed, and the time taken for each segment of the journey.

Given information: - Initial speed: 180 km/h - Increased speed: 85 km/h - Time taken at the initial speed: 3 hours - Time taken at the increased speed: 1 hour

To calculate the distance traveled at the initial speed, we can use the formula:

Distance = Speed × Time

Substituting the values, we have:

Distance at initial speed = 180 km/h × 3 hours

To calculate the distance traveled at the increased speed, we can use the same formula:

Distance = Speed × Time

Substituting the values, we have:

Distance at increased speed = (180 km/h + 85 km/h) × 1 hour

Finally, to calculate the total distance traveled by the train, we add the distances traveled at the initial speed and the increased speed:

Total distance = Distance at initial speed + Distance at increased speed

Let's calculate the distances:

Distance at initial speed = 180 km/h × 3 hours = 540 km Distance at increased speed = (180 km/h + 85 km/h) × 1 hour = 265 km Total distance = 540 km + 265 km = 805 km

Therefore, the train traveled a total distance of 805 kilometers.
