Question

поезд-экспресс шёл 3ч со скорстью 180км/ч.Затем он увиличил скорость на85км/ч и через час прибыл на конечную станцию.Какой путь прошёл поезд

Answer 1

180•3+85=625кажется)

Answer 2

1) 3 * 180 = 540 км прошел за 3 часа
2) 180 + 85 = 265 км/ч скорость после увеличения
3) 265 * 1 = 265 км прошел за 1 час после увеличения скорости
4) 540 + 265 = 805 км прошел поезд

Answer 3

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 for the first segment: 3 hours - Time taken for the second segment: 1 hour

To calculate the distance traveled during the first segment, we can use the formula:

Distance = Speed × Time

For the first segment: - Speed = 180 km/h - Time = 3 hours

Using the formula, we can calculate the distance traveled during the first segment:

Distance1 = 180 km/h × 3 hours

Now, to calculate the distance traveled during the second segment, we need to consider the increased speed. The formula remains the same:

Distance = Speed × Time

For the second segment: - Speed = 180 km/h + 85 km/h (increased speed) - Time = 1 hour

Using the formula, we can calculate the distance traveled during the second segment:

Distance2 = (180 km/h + 85 km/h) × 1 hour

Finally, to find the total distance traveled by the train, we add the distances of both segments:

Total Distance = Distance1 + Distance2

Let's calculate the distances:

Distance1 = 180 km/h × 3 hours = 540 km Distance2 = (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.
