Question

Реши задачи. б)Средняя скорость самолёта 500км/ч,что в 10 раз больше скорости поезда.А скорость велосипедиста на 35км/ч меньше скорости поезда.Чему равна скорость велосипедиста? помогите пж четвертная контрольная здавать через 4 минуты пж

Answer 1

500 : 10 =50км Vпоезда
50-35 =15 км Vвелосипедиста

Answer 2

500:10= 50 - скорость поезда
50-35=15 км
Ответ скорость велосипедиста равна 15 км

Problem Analysis

We are given that the average speed of an airplane is 500 km/h, which is 10 times faster than the speed of a train. Additionally, the speed of a cyclist is 35 km/h less than the speed of the train. We need to find the speed of the cyclist.

Solution

Let's assume the speed of the train is x km/h.

According to the given information, the speed of the airplane is 10 times faster than the speed of the train. Therefore, the speed of the airplane is 10x km/h.

The speed of the cyclist is 35 km/h less than the speed of the train. Therefore, the speed of the cyclist is (x - 35) km/h.

To find the value of x, we can set up an equation using the given information:

10x = 500

Solving this equation, we find that x = 50 km/h.

Now, we can substitute the value of x into the equation for the speed of the cyclist:

(x - 35) = (50 - 35) = 15 km/h.

Therefore, the speed of the cyclist is 15 km/h.

Answer

The speed of the cyclist is 15 km/h.
