Question

Автомобилист ехал до соседнего города 4 часа со скоростью 52 км ч На обратном пути он увеличил скорость в 2 раза сколько времени длилась

Answer 1

1)52*4=208 (км)-расстояние до города

2)52*2=104 (км/ч)-он ехал обратно

 3)208:104=2 (ч)-он ехел обратно

4)2+4=6 (ч)-длилась поездка туда и обратно

Ответ:6 часов длилась поездка туда и обратно

Answer 2

Расстояние: 4 · 52 = 208 км.

Скорость на обратном пути: 52 · 2 = 104 км/ч.

Время: 208 : 104 = 2 ч.

Ответ: 2 часа.

Answer 3

Calculation of Time Duration

To calculate the duration of the return trip, we need to consider the following information:

- The driver traveled to the neighboring city for 4 hours at a speed of 52 km/h. - On the return trip, the driver increased the speed by 2 times.

Let's calculate the time duration of the return trip:

The distance traveled during the initial trip can be calculated using the formula:

Distance = Speed × Time

Given that the speed during the initial trip was 52 km/h and the time was 4 hours, we can calculate the distance:

Distance = 52 km/h × 4 hours = 208 km

Now, let's calculate the time duration of the return trip. Since the speed was doubled, the new speed is 52 km/h × 2 = 104 km/h.

Using the formula:

Time = Distance / Speed

we can calculate the time duration of the return trip:

Time = 208 km / 104 km/h = 2 hours

Therefore, the return trip lasted 2 hours.
