Question

В полдень от пристани отошло пароход со скоростью 16 км/час. Через три часа от этой же пристани в том же направлении отошел второй пароход и через 12 часов выхода догнал первый пароход. Найди скорость второго парохода

Answer 1

1)3+12=15 час был в пути первый параход

2)15*16=240 км прошли параходы 

3)240:12=20 км/час скорость второго

Answer 2

Calculation of the Second Ship's Speed

To find the speed of the second ship, we can use the formula:

Speed = Distance / Time

Let's calculate the distance traveled by the first ship in 3 hours. The speed of the first ship is given as 16 km/h.

Distance = Speed * Time

Distance = 16 km/h * 3 hours

Distance = 48 km

Now, let's calculate the time it took for the second ship to catch up to the first ship. The time is given as 12 hours.

Since the second ship caught up to the first ship, the distance traveled by both ships must be the same.

Distance of the second ship = Distance of the first ship

Speed of the second ship * Time of the second ship = Distance of the first ship

Speed of the second ship * 12 hours = 48 km

Now, we can solve for the speed of the second ship:

Speed of the second ship = 48 km / 12 hours

Speed of the second ship = 4 km/h

Therefore, the speed of the second ship is 4 km/h.
