Question

Поезд скорость которого 30 км/ч приходит путь от Уфы до стерлитомака за 6 часов за сколько часов автомобили проедет половио этого пути если будет двиготся со скоростью 45 км/ч? запиши решение и ответ

Answer 1

30*6=180 км - всё расстояние
180:2=90 км - полпути
90:45=2 часа - время которое преодалеет за пол пути

Answer 2

Problem Analysis

We are given that a train with a speed of 30 km/h takes 6 hours to travel from Ufa to Sterlitamak. We need to find out how many hours it will take for a car traveling at a speed of 45 km/h to cover half of this distance.

Solution

To solve this problem, we can use the formula:

Time = Distance / Speed

Let's calculate the distance traveled by the train using the given information:

Distance = Speed × Time

Distance = 30 km/h × 6 hours

Distance = 180 km

Now, we need to find out how many hours it will take for a car traveling at a speed of 45 km/h to cover half of this distance.

Distance for the car = 180 km / 2 = 90 km

Using the formula mentioned earlier, we can find the time taken by the car:

Time = Distance / Speed

Time = 90 km / 45 km/h

Time = 2 hours

Therefore, the car will take 2 hours to cover half of the distance traveled by the train.

Answer

The car will take 2 hours to cover half of the distance traveled by the train.

Calculation Steps

1. Calculate the distance traveled by the train: Distance = Speed × Time = 30 km/h × 6 hours = 180 km 2. Calculate the distance for the car: Distance for the car = 180 km / 2 = 90 km 3. Calculate the time taken by the car: Time = Distance / Speed = 90 km / 45 km/h = 2 hours
