Question

Пароход прошёл путь между пристанями за 8 часов со скоростью 30 км/час. На обратном пути то же расстояние теплоход прошёл за 6 часов. С какой скоростью шёл теплоход на обратном пути?

Answer 1

40 км/час это очень легко!

Answer 2

1) 30*8=240(км.) - расстояние между пристанями.
2) 240/6=40(км./ч.) - скорость теплохода на обратном пути.
Ответ: 40 км./ч.

Answer 3

Calculating the Speed of the Ship on the Return Trip

To calculate the speed of the ship on the return trip, we can use the formula: Speed = Distance / Time

Given: - The ship covered the distance between the ports in 8 hours at a speed of 30 km/h on the outbound trip. - The same distance was covered in 6 hours on the return trip.

Using the formula, we can calculate the speed of the ship on the return trip:

Speed = Distance / Time

Speed = Distance / 6 hours

Now, we need to find the distance covered by the ship. We can use the fact that the ship's speed on the outbound trip was 30 km/h.

Calculating the Distance Covered

Using the speed and time taken on the outbound trip, we can calculate the distance covered:

Distance = Speed * Time

Distance = 30 km/h * 8 hours

Calculating the Speed on the Return Trip

Now that we have the distance, we can use it to calculate the speed on the return trip:

Speed = Distance / 6 hours

Speed = (30 km/h * 8 hours) / 6 hours

Speed = 40 km/h

Therefore, the speed of the ship on the return trip was 40 km/h.
