Question

грузовой фургон проехал треть пути со скоростью 90км/ч за 8 ч сколько осталось проехать.. сколько времени займёт остальной путь если фургон будет ехать с той же скоростью?

Answer 1

1)90*8=720(км)-проиденное расстояние                                                          2)720*2=1440(км)-2/3 пути-остальной путь                                                      3)1440/90=16(ч)-оставшееся время                                                                           Ответ: 16 ч займёт остальной путь.

Answer 2

Calculation of Remaining Distance and Time

To calculate the remaining distance and time for the cargo van, we need to know the initial total distance and the speed at which it is traveling. From the given information, we know that the cargo van has already traveled one-third of the total distance at a speed of 90 km/h for 8 hours.

Let's assume the total distance is D km.

The distance covered by the cargo van in 8 hours at a speed of 90 km/h is given by the formula:

Distance = Speed × Time

Substituting the values, we have:

D/3 = 90 × 8

Simplifying the equation, we find:

D/3 = 720

Multiplying both sides of the equation by 3, we get:

D = 2160

Therefore, the total distance is 2160 km.

To calculate the remaining distance, we subtract the distance already covered from the total distance:

Remaining Distance = Total Distance - Distance Covered

Remaining Distance = 2160 - (D/3)

Substituting the value of D, we have:

Remaining Distance = 2160 - (2160/3)

Simplifying the equation, we find:

Remaining Distance = 2160 - 720

Remaining Distance = 1440 km

So, the remaining distance for the cargo van to travel is 1440 km.

To calculate the time it will take to cover the remaining distance at the same speed of 90 km/h, we use the formula:

Time = Distance / Speed

Substituting the values, we have:

Time = 1440 / 90

Simplifying the equation, we find:

Time = 16 hours

Therefore, it will take the cargo van an additional 16 hours to cover the remaining distance of 1440 km at a speed of 90 km/h.

Summary:

- The total distance is 2160 km. - The remaining distance for the cargo van to travel is 1440 km. - It will take the cargo van an additional 16 hours to cover the remaining distance at a speed of 90 km/h.
