Question

Велосипедист проехал 36 км, двигаясь со скоростью 18 км/ч, и сделал остановку. После остановки он ехал столько же часов со скоростью 15 км/ч. Сколько ки- лометров проехал велосипедист после остановки?​

Answer 1

Ответ:

вот<3

Пошаговое объяснение:

1. Определим какое расстояние проехал велосипедист после остановки.

60 - 24 = 36 километров.

2. Узнаем сколько всего километров проехал велосипедист.

60 + 36 = 96 километров.

3. Вычислим с какой скоростью в час он ехал, если известно, что 96 километров он преодолел за 8 часов.

96 / 8 = 12 километров.

4. Узнаем сколько времени он провел в пути до остановки.

60 / 12 = 5 часа.

Ответ: Велосипедист до того как сделал остановку ехал 5 часов.

Answer 2

Calculating Distance Traveled by the Cyclist

To calculate the distance traveled by the cyclist after the stop, we can use the formula:

Distance = Speed × Time

First, let's calculate the distance traveled at the initial speed of 18 km/h and then the distance traveled at the reduced speed of 15 km/h.

1. Distance Traveled at 18 km/h: - Speed: 18 km/h - Time: Given as unspecified - Distance: To be calculated

2. Distance Traveled at 15 km/h: - Speed: 15 km/h - Time: Given as the same as the time at the initial speed - Distance: To be calculated

Let's calculate the distances using the given information.

Distance Traveled at 18 km/h

Using the formula Distance = Speed × Time, we can calculate the distance traveled at 18 km/h.

Distance = 18 km/h × Time

Distance Traveled at 15 km/h

The cyclist traveled the same amount of time at 15 km/h as at 18 km/h.

Distance = 15 km/h × Time

Now, let's calculate the distances using the given speeds and the same amount of time.

Calculating the Distances

Given that the cyclist traveled the same amount of time at both speeds, we can use the fact that the distances are directly proportional to the speeds.

Distance at 18 km/h / Distance at 15 km/h = 18 / 15

This allows us to find the ratio of the distances traveled at the two different speeds.

Solution

By solving the above equation, we can find the distance traveled at 15 km/h in terms of the distance traveled at 18 km/h.

Distance at 15 km/h = (15/18) × Distance at 18 km/h

Substituting the given distance at 18 km/h (36 km), we can calculate the distance traveled at 15 km/h.

Distance at 15 km/h = (15/18) × 36 km

Distance at 15 km/h = 30 km

So, the cyclist traveled 30 kilometers after the stop at a speed of 15 km/h.

This calculation is based on the given speeds and the same amount of time traveled at each speed
