Question

Витя ехал от города до села на грузовой машине со скоростью 40 км/ ч .Обратный путь он ехал на легковой машине со скоростью 70 км/ ч. Сколько времени Витя ехал из города в село, если на обратный путь он затратил 4 ч?

Answer 1

70×4=280 км расстояние от города до села
280:40=7 ч Витя ехал на грузовой машине

Answer 2

Calculation of Travel Time

To calculate the travel time from the city to the village, we need to determine the distance between the two locations. Unfortunately, the provided question does not include the distance. However, we can still calculate the time using the given speeds.

Vitya traveled from the city to the village at a speed of 40 km/h on a truck, and on the return journey, he traveled at a speed of 70 km/h on a car. We also know that the return journey took 4 hours.

Let's assume the distance between the city and the village is d kilometers.

To calculate the time it took for Vitya to travel from the city to the village, we can use the formula:

Time = Distance / Speed

For the first leg of the journey (city to village), the time can be calculated as:

Time1 = d / 40

For the return journey (village to city), the time is given as 4 hours:

Time2 = 4

Since the distance traveled in both directions is the same, we can equate the two times:

Time1 = Time2

d / 40 = 4

Now, we can solve this equation to find the value of d.

Calculation:

d / 40 = 4

Multiplying both sides of the equation by 40:

d = 4 * 40

d = 160

Therefore, the distance between the city and the village is 160 kilometers.

Now, we can calculate the time it took for Vitya to travel from the city to the village using the distance and speed:

Time1 = 160 / 40

Time1 = 4 hours

So, Vitya took 4 hours to travel from the city to the village.

Please note that the distance between the city and the village is assumed based on the given information. If the actual distance is different, the travel time will also be different.
