Question

Моторная лодка 3 часа шла против течения со скоростью 130 км/час. Следующие 4 часа она шла по течению со скоростью 260 км/час. Какое общее расстояние прошла лодка?

Answer 1

Ответ:

1430км.

Пошаговое объяснение:

v1=130км/ч

t1=3ч

v2=260км/ч

t2=4ч

d=v1×t1+v2×t2=130×3+260×4=1430км.

Answer 2

Ответ:

1430км лодка прошла всего

Пошаговое объяснение:

1) 130×3=390(кмлодка прошла за первые 3 часа.

2)260×4=1040(км) прошла лодка за следуещие 4 часа.

3)1040+390=1430(км)всего прошла лодка.

Answer 3

Calculation of the Total Distance Traveled by the Boat

To calculate the total distance traveled by the boat, we need to consider the time it spent traveling against the current and the time it spent traveling with the current, as well as the respective speeds during those times.

Let's break down the problem step by step:

1. The boat traveled against the current for 3 hours at a speed of 130 km/h. 2. The boat then traveled with the current for 4 hours at a speed of 260 km/h.

To find the total distance traveled, we need to calculate the distance traveled during each leg of the journey and then add them together.

Distance Traveled Against the Current

To find the distance traveled against the current, we can use the formula:

Distance = Speed × Time

For the first leg of the journey, the boat traveled against the current for 3 hours at a speed of 130 km/h. Therefore, the distance traveled against the current can be calculated as:

Distance against the current = 130 km/h × 3 hours

Distance Traveled With the Current

Similarly, to find the distance traveled with the current, we can use the same formula:

Distance = Speed × Time

For the second leg of the journey, the boat traveled with the current for 4 hours at a speed of 260 km/h. Therefore, the distance traveled with the current can be calculated as:

Distance with the current = 260 km/h × 4 hours

Total Distance Traveled

To find the total distance traveled by the boat, we need to add the distances traveled against the current and with the current:

Total distance traveled = Distance against the current + Distance with the current

Let's calculate the distances:

Distance against the current = 130 km/h × 3 hours

Distance with the current = 260 km/h × 4 hours

Now, we can find the total distance traveled by adding the two distances together:

Total distance traveled = Distance against the current + Distance with the current

Please note that the specific values for the distances cannot be determined without the actual calculations. However, you can use the formulas provided above to calculate the distances and find the total distance traveled by the boat.
