Question

Путешествинники проехали всего 860 км,из них на автобусе на 460 км меньше,чем на поезде. Сколько часов они были в пути , если скорость автобуса 50 км/ч, а поезда - 66 км/ч?

Answer 1

(860-460):2=400:2=200км проехали на автобусе                                                       460+200=660 км проехали на поезде                                                                        660:66=11 часов ехали на поезде                                                                             200:50=4 часа ехали на автобусе                                                                             11+4=15 часов были в пути                                                                                       Ответ: Путешественники 15 часов были в пути

Answer 2

Calculating Travel Time for the Journey

To calculate the travel time for the journey, we can use the following steps:

1. Calculate the distance traveled by the train. 2. Calculate the time taken by the train to cover its distance. 3. Calculate the distance traveled by the bus. 4. Calculate the time taken by the bus to cover its distance. 5. Add the times taken by the train and the bus to get the total travel time.

Calculating Distance and Time for the Train

The distance traveled by the train can be calculated using the formula: distance = speed × time

Given: - Speed of the train = 66 km/h - Let the time taken by the train be represented by t hours

Using the formula, we can calculate the distance traveled by the train: distance = 66t

Calculating Distance and Time for the Bus

The distance traveled by the bus can be calculated using the formula: distance = speed × time

Given: - Speed of the bus = 50 km/h - The distance traveled by the bus is 460 km less than the distance traveled by the train.

Using the formula, we can calculate the distance traveled by the bus: distance = 66t - 460

To find the time taken by the bus, we can use the formula: time = distance / speed

Total Travel Time

The total travel time can be calculated by adding the time taken by the train and the time taken by the bus.

Let's calculate the time taken by the train and the bus and then find the total travel time.
