Question

Из одного города в другой вышел человек. человек прошел 27км, потом за ним выехал автобус со скоростью в 10 раз больше, чем у человека. какое расстояние между городами

Answer 1

30 киллометров
Пешеход затратил на второй отрезок пути Х времени
А автомобиль затратил навесь пусть Х времени, т. к. они прибыли одновременно.
Скорость пешехода равна У км/ч
Значит у автомобиля 10У км/час
Всего они прошли путь
пешеход = 27 км. + Х*У
автомобиль = 10*Х*У
При том что они прошли равный путь можно составить равенство
27 + Х*У = 10*Х*У
9ХУ=27
ХУ=3= длинна второго отрезка пути пешехода. Значит расстояние между городами равно
27+3=30

Answer 2

Calculating the Distance Between Two Cities

To calculate the distance between two cities given the information provided, we can use the formula: distance = speed * time. Let's break down the information given and calculate the distance.

1. Distance Walked by the Person: - The person walked 27 km.

2. Speed of the Bus: - The bus's speed is 10 times greater than the person's speed.

To calculate the total distance between the two cities, we can use the formula: total distance = distance walked by the person + distance covered by the bus.

Calculating the Total Distance

Using the information provided: - Distance walked by the person = 27 km - Speed of the bus = 10 times the person's speed

We can calculate the distance covered by the bus: distance covered by the bus = speed of the bus * time taken by the bus

Since the time taken by the bus is not provided, we'll use the formula: time = distance / speed

Let's calculate the distance covered by the bus and then find the total distance between the two cities.

Calculation

- Distance walked by the person = 27 km - Speed of the bus = 10 times the person's speed

Using the given information, we can calculate the distance covered by the bus: time taken by the person = distance walked by the person / speed of the person time taken by the bus = distance covered by the bus / speed of the bus

Now, we can calculate the distance covered by the bus and then find the total distance between the two cities.

Conclusion

Based on the information provided, the total distance between the two cities can be calculated using the distance walked by the person and the distance covered by the bus. If the time taken by the bus is provided, the total distance can be accurately calculated.
