Question

из пунктов А и В расстояние между которыми 200 км одновременно выехал один турист на автобусе со скоростью 40 км/ч а другой на автомобиле найдите скорость автомобиля зная что они встретелись через 2 часа

Answer 1

40*2=80км

200-80=120км

120/2=60км/ч

скорость автомобиля 60км/ч

 

Answer 2

Скоростьь автомобиля

200-40=160

Answer 3

Problem Analysis

Two tourists start from points A and B, which are 200 km apart. One tourist travels by bus at a speed of 40 km/h, while the other travels by car. They meet after 2 hours. We need to find the speed of the car.

Solution

Let's assume the speed of the car is v km/h.

The distance traveled by the bus in 2 hours is given by: Distance_bus = Speed_bus * Time = 40 km/h * 2 hours = 80 km.

The distance traveled by the car in 2 hours is given by: Distance_car = Speed_car * Time = v km/h * 2 hours = 2v km.

Since the total distance between points A and B is 200 km, we can write the equation: Distance_bus + Distance_car = 200 km.

Substituting the values of Distance_bus and Distance_car, we get: 80 km + 2v km = 200 km.

Simplifying the equation, we have: 2v km = 200 km - 80 km, 2v km = 120 km, v km = 120 km / 2, v km = 60 km/h.

Therefore, the speed of the car is 60 km/h.

Answer

The speed of the car is 60 km/h.

Explanation

Two tourists start from points A and B, which are 200 km apart. One tourist travels by bus at a speed of 40 km/h, while the other travels by car. They meet after 2 hours. To find the speed of the car, we can use the equation Distance_bus + Distance_car = 200 km. By substituting the values and solving the equation, we find that the speed of the car is 60 km/h
