Question

Утром от пристани отошел теплоход со скоростью 18 км/ч. через 4 часа вслед ему отощёл другой теплоход и через 8 часов догнал первый. какова скорость второго теплохода

Answer 1

Мы знаем что второй теплоход стал догонять второго через 4 часа когда отъехал первый так что:1)18  * 4 = 72(км.) расстояние 1 теплохода

2) 72 : 8 = 9 (км\ч.) скорость второго теплохода
всё:) Ответ : 9 км. в час
 

Answer 2

Calculation of the Second Ship's Speed

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

Speed = Distance / Time

Let's assume that the distance between the two ships is D kilometers.

The first ship travels at a speed of 18 km/h for 4 hours, so it covers a distance of 18 * 4 = 72 kilometers.

The second ship catches up to the first ship after 8 hours.

Since the second ship catches up to the first ship, the distance traveled by the second ship is equal to the distance traveled by the first ship plus the distance between the two ships.

Therefore, the distance traveled by the second ship is 72 + D kilometers.

The time taken by the second ship to cover this distance is 8 hours.

Using the formula mentioned earlier, we can write the equation:

Speed of the second ship = (72 + D) / 8

Unfortunately, the search results provided do not contain the necessary information to determine the value of D or calculate the exact speed of the second ship.
