Answer 1

Ответ:

12км/ч

Пошаговое объяснение:

через час пройденное пешеходам расстояние будет равняться 4 км.

1)4*1=4км

так как расстояние между ними было 8 км

2)8+4=12км

12 километров должен был проехать велосипедист чтобы догнать пешехода

1)12:1=12км/ч

Answer 2

Problem Analysis

We are given that a pedestrian is walking on a road with a speed of 4 km/h, and a cyclist is following the pedestrian. The distance between them is 8 km. After one hour, the cyclist catches up to the pedestrian. We need to determine the speed of the cyclist.

Solution

To find the speed of the cyclist, we can use the formula:

Speed = Distance / Time

In this case, the distance between the cyclist and the pedestrian is 8 km, and the time taken for the cyclist to catch up to the pedestrian is 1 hour. Plugging these values into the formula, we can calculate the speed of the cyclist.

Calculation

Using the formula Speed = Distance / Time, we can calculate the speed of the cyclist:

Speed = 8 km / 1 hour

Therefore, the speed of the cyclist is 8 km/h.

Answer

The speed of the cyclist is 8 km/h.
