Question

Решение задачи: автобус ехал 3 ч со скоростью 54 км/ ч. Проехал он 9/14 всего пути. Сколько всего км он должен проехать? С какой. скоростью надо ехать автобусу, чтобы преодолеть оставшееся расстояние за 2 часа?

Answer 1

3*54=162км.- автобус проехал за 3 часа
162км. это 9/14 пути, узнаем весь путь:
162:9*14=252км. - весь путь.
252-162=90км. - автобусу осталось проехать 90км., чтобы проехать это расстояние за 2 часа ему нужно ехать со скоростью 90:2=45км/ч.

Answer 2

Task Solution:

The bus traveled for 3 hours at a speed of 54 km/h and covered 9/14 of the total distance. We need to find the total distance it should cover and the speed it needs to travel to cover the remaining distance in 2 hours.

Step 1: Calculate the Total Distance Traveled by the Bus:

To find the total distance the bus should cover, we can use the formula: \[ \text{Distance} = \text{Speed} \times \text{Time} \]

Given that the bus traveled for 3 hours at a speed of 54 km/h, we can calculate the distance it covered: \[ \text{Distance} = 54 \, \text{km/h} \times 3 \, \text{h} \]

The total distance the bus should cover is 162 km.

Step 2: Calculate the Remaining Distance:

To find the remaining distance, we can use the fact that the bus covered 9/14 of the total distance. We can calculate the remaining distance as: \[ \text{Remaining Distance} = \text{Total Distance} - \text{Distance Covered} \] \[ \text{Remaining Distance} = 162 \, \text{km} - \left( \frac{9}{14} \times 162 \, \text{km} \right) \]

The remaining distance is 54 km.

Step 3: Calculate the Required Speed to Cover the Remaining Distance in 2 Hours:

To find the speed the bus needs to travel to cover the remaining distance in 2 hours, we can use the formula: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \] \[ \text{Speed} = \frac{54 \, \text{km}}{2 \, \text{h}} \]

The bus needs to travel at a speed of 27 km/h to cover the remaining distance in 2 hours.

Therefore, the bus should cover a total distance of 162 km and needs to travel at a speed of 27 km/h to cover the remaining distance in 2 hours.
