Question

Теплоход шел 2,5 ч по течению реки и 3,2 ч против течения.Какой общий путь прошёл теплоход,если его собственная скорость 22км/ч,а скорость течения 3км/ч?

Answer 1

22+3=25км/ч скорость теплохода по течению
22-3=19 км/ч скорость против течения
25*2,5=60,8 км прошел по течению
19*3,2=62,5 км прошел против течения
60,8+62,5=123,3 км общий путь

Answer 2

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 took for the boat to travel both with and against the current.

Given: - Time taken to travel with the current: 2.5 hours - Time taken to travel against the current: 3.2 hours - Boat's own speed: 22 km/h - Speed of the current: 3 km/h

To find the total distance traveled, we can use the formula:

Distance = Speed x Time

Let's calculate the distance traveled with the current first:

Distance with current = Speed with current x Time with current

The speed with the current is the sum of the boat's own speed and the speed of the current:

Speed with current = Boat's own speed + Speed of the current

Substituting the given values:

Speed with current = 22 km/h + 3 km/h = 25 km/h

Now, we can calculate the distance traveled with the current:

Distance with current = 25 km/h x 2.5 hours = 62.5 km Next, let's calculate the distance traveled against the current:

Distance against current = Speed against current x Time against current

The speed against the current is the difference between the boat's own speed and the speed of the current:

Speed against current = Boat's own speed - Speed of the current

Substituting the given values:

Speed against current = 22 km/h - 3 km/h = 19 km/h

Now, we can calculate the distance traveled against the current:

Distance against current = 19 km/h x 3.2 hours = 60.8 km Finally, to find the total distance traveled, we add the distances traveled with and against the current:

Total distance traveled = Distance with current + Distance against current

Substituting the calculated values:

Total distance traveled = 62.5 km + 60.8 km = 123.3 km

Therefore, the total distance traveled by the boat is approximately 123.3 kilometers.
