Question

Первые 2ч автомобиль ехал со скоростью 60км/ч,а в следующие 3ч увеличил скорость на 10км/ч.Какое расстояние проехал автомобиль ? Сколько километров ему ещё осталось проехать , если весь путь автомобиля равен 350км?

Answer 1

1) 2*60 = 120 (км)
2) 3*(60+10) = 3*70 = 210 (км)
3) 120 + 210 = 330 (км) - проехал автомобиль
4) 350 - 330 = 20 (км) - осталось проехать автомобилю

Answer 2

Calculation of Distance Traveled

To calculate the distance traveled by the car, we need to determine the distance covered during the first 2 hours and the distance covered during the next 3 hours.

The car traveled at a speed of 60 km/h for the first 2 hours. Therefore, the distance covered during this time can be calculated using the formula:

Distance = Speed × Time

Substituting the given values, we have:

Distance1 = 60 km/h × 2 hours

Now, let's calculate the distance covered during the next 3 hours. The car increased its speed by 10 km/h, so the new speed is 60 km/h + 10 km/h = 70 km/h. Using the same formula as before:

Distance2 = 70 km/h × 3 hours

To find the total distance traveled by the car, we add the distances covered during the first 2 hours and the next 3 hours:

Total Distance = Distance1 + Distance2

Now, let's calculate the values:

Distance1 = 60 km/h × 2 hours = 120 km.

Distance2 = 70 km/h × 3 hours = 210 km.

Total Distance = Distance1 + Distance2 = 120 km + 210 km = 330 km.

Therefore, the car traveled a total distance of 330 km.

Remaining Distance

To find the remaining distance the car has to travel, we subtract the total distance traveled from the initial distance of 350 km:

Remaining Distance = Initial Distance - Total Distance

Substituting the values:

Remaining Distance = 350 km - 330 km = 20 km.

Therefore, the car has 20 km left to travel.

In summary: - The car traveled a total distance of 330 km. - The car has 20 km left to travel.
