Question

Расстояние между двумя селами 12.2 км.в одном направлении выехал мотоцикл и вышел пешеход.мотоцикл ехал со скоростью 10.2 км/час,догнал пешех.через 2 часа .найдите скорость пешехода

Answer 1

1) 12,2 : 2 = 6,1 км/ч - скорость сближения пешехода и велосипедиста
2)) 10,2 - 6,1 = 4,1 км/ч - скорость пешехода

Answer 2

Problem Analysis

We are given that the distance between two villages is 12.2 km. A motorcycle starts from one village and a pedestrian starts from the other village. The motorcycle travels at a speed of 10.2 km/h and catches up with the pedestrian after 2 hours. We need to find the speed of the pedestrian.

Solution

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

We can calculate the time it takes for the motorcycle to catch up with the pedestrian using the formula:

Time = Distance / Speed

The distance traveled by the motorcycle in 2 hours is:

Distance = Speed * Time

Substituting the values we have:

12.2 km = 10.2 km/h * 2 hours

Simplifying the equation:

12.2 km = 20.4 km

This equation is not true, so there seems to be an error in the given information or calculations.
