Question

Расстояние между поселками А и В равно 24 км. Из поселка А по направлению к поселку В выехал автобус. Одновременно с ним из поселка В в том же направлении выехал велосипедист. Автобус через 0,6 ч догнал велосипедиста на расстоянии 9 км от поселка В. С какой скоростью ехал автобус и какова скорость велосипедиста?решите, плз, и подписывайте возле решенных действий что это означает

Answer 1

1) 24+9=33 (км) - проехал автобус за 0,6 часа

2) 33:0,6=55 (км/ч) - скорость автобуса

3) 9:0,6=15 (км/ч) - скорость велосипедиста

Ответ: скорость автобуса 55 км/ч, велосипедиста - 15 км/ч.

Answer 2

Problem Analysis

We are given that the distance between two villages, A and B, is 24 km. An bus starts from village A towards village B, and at the same time, a cyclist starts from village B in the same direction. After 0.6 hours, the bus overtakes the cyclist at a distance of 9 km from village B. We need to find the speeds of the bus and the cyclist.

Solution

Let's assume the speed of the bus is x km/h and the speed of the cyclist is y km/h.

To solve this problem, we can use the formula: speed = distance / time.

We know that the distance between the bus and the cyclist when the bus overtakes the cyclist is 9 km. We also know that the time taken by the bus to overtake the cyclist is 0.6 hours.

Using the formula, we can write the following equations:

1. For the bus: x = 9 / 0.6 (since the distance covered by the bus is 9 km in 0.6 hours) 2. For the cyclist: y = 24 - 9 / 0.6 (since the distance covered by the cyclist is the remaining distance between the two villages)

Now, let's calculate the values of x and y.

Calculation

1. For the bus: - x = 9 / 0.6 - x = 15 km/h

2. For the cyclist: - y = 24 - 9 / 0.6 - y = 15 km/h

Answer

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