Question

Половину пуйти авто проехал 6 часов со скорастью 70 а остальное растойание -со скорастью 105 . сколько времени автомабиль находиться в пути?

Answer 1

6*70=420 км это половина пути значит и вторая половина тоже 420 км
420:105=4 часа на вторую половину пути
6+4=10часов автомобиль находился в пути

Answer 2

Calculation of Time Taken by the Car

To calculate the time taken by the car, we need to consider the distances traveled at different speeds.

Let's assume that the car traveled half of the distance at a speed of 70 km/h and the remaining distance at a speed of 105 km/h.

To calculate the time taken for each part of the journey, we can use the formula:

Time = Distance / Speed

Let's calculate the time taken for each part of the journey:

1. Time taken for the first half of the journey at a speed of 70 km/h: - Distance = Half of the total distance - Speed = 70 km/h - Time = Distance / Speed

2. Time taken for the second half of the journey at a speed of 105 km/h: - Distance = Remaining distance (which is also half of the total distance) - Speed = 105 km/h - Time = Distance / Speed

To find the total time taken, we can add the times taken for each part of the journey.

Let's calculate the time taken by the car:

1. Time taken for the first half of the journey at a speed of 70 km/h: - Distance = Half of the total distance - Speed = 70 km/h - Time = Distance / Speed

2. Time taken for the second half of the journey at a speed of 105 km/h: - Distance = Remaining distance (which is also half of the total distance) - Speed = 105 km/h - Time = Distance / Speed

3. Total time taken: - Total time = Time taken for the first half + Time taken for the second half

Let's calculate the time taken by the car using the given information:

1. Time taken for the first half of the journey at a speed of 70 km/h: - Distance = Half of the total distance = 6 hours * 70 km/h = 420 km - Speed = 70 km/h - Time = Distance / Speed = 420 km / 70 km/h = 6 hours

2. Time taken for the second half of the journey at a speed of 105 km/h: - Distance = Remaining distance (which is also half of the total distance) = 420 km - Speed = 105 km/h - Time = Distance / Speed = 420 km / 105 km/h = 4 hours

3. Total time taken: - Total time = Time taken for the first half + Time taken for the second half = 6 hours + 4 hours = 10 hours

Therefore, the car will be on the road for 10 hours.
