Question

Половину пути автомобиль проехал за 6ч со скоростью 70км/ч, а остальное расстояние --- со скоростью 105км/ч. Сколько времени автомобиль находился в пути?

Answer 1

1) 70×6=420 (км)- путь, который проехал автомобиль за 6 часов
2) 420:105= 4(ч)- столько времени автомобиль затратил на вторую половину пути
3) 4+6=10(ч)- столько времени авто находилось в пути

Answer 2

Calculation of Total Time

To calculate the total time the car was in motion, we need to determine the distances traveled at each speed and then divide each distance by its corresponding speed to find the time taken. Finally, we add the two times together to get the total time.

Let's break down the problem:

- The car traveled the first half of the distance at a speed of 70 km/h for 6 hours. - The remaining distance was covered at a speed of 105 km/h.

To find the total time, we need to calculate the time taken for each part of the journey.

Time taken for the first half of the distance

The car traveled the first half of the distance at a speed of 70 km/h for 6 hours. To find the distance traveled during this time, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled during the first 6 hours:

Distance = 70 km/h × 6 hours

Now, let's calculate the time taken for this distance:

Time = Distance / Speed

Time taken for the remaining distance

The remaining distance was covered at a speed of 105 km/h. To find the time taken for this distance, we can use the same formula:

Time = Distance / Speed

Now, let's calculate the time taken for the remaining distance.

Total time

To find the total time, we add the time taken for the first half of the distance and the time taken for the remaining distance.

Let's calculate the total time.

Note: The exact values for the distances and times are not provided in the question. We can only provide a general method to calculate the total time based on the given information.
