Question

Срочно!!! Дам 20 баллов!!!Длинна маршрута 400 км. Турист ехал 4 ч поездом со скоростью х км/ч и 3 ч автобусом со скоростью 70 км/ч. За сколько часов он пройдёт остаток пути пешком, если будет идти со скоростью 4 км/ч???

Answer 1

4х-путь на поезде
3*70=210 путь на автобусе
400-4х-210 остаток пути
(400-4х-210)/4 Сколько ему осталось идти
Ответ:(400-4х-210)/4

Answer 2

Calculating Time to Cover Remaining Distance

To calculate the time it will take for the tourist to cover the remaining distance on foot, we can use the formula: time = distance / speed.

Given: - Length of the route = 400 km - Time traveled by train = 4 hours - Speed of the train = x km/h - Time traveled by bus = 3 hours - Speed of the bus = 70 km/h - Speed of walking = 4 km/h

First, let's calculate the distance covered by the train and the bus: - Distance covered by the train = speed of the train * time traveled by train - Distance covered by the bus = speed of the bus * time traveled by bus

The total distance covered by the train and the bus can be calculated by adding these two distances and subtracting it from the total length of the route.

The remaining distance can then be divided by the walking speed to find the time required to cover it.

Calculations

- Distance covered by the train = x km/h * 4 h - Distance covered by the bus = 70 km/h * 3 h - Total distance covered by train and bus = (x * 4) + (70 * 3) km - Remaining distance = 400 km - (x * 4) - (70 * 3) km - Time to cover remaining distance on foot = Remaining distance / Walking speed

Let's calculate the time to cover the remaining distance.
