Question

От пристани отошел теплоход 18 км/ч через 3 часа в том же направлении отошел второй теплоход который догнал первый через 9 часов после выхода Найти скорость второго теплохода

Answer 1

9+3=12ЧАСОВ    18*12=216 КМ ПЕРВЫЙ ПЕПЛОХОД   216*9=24 КМ  ВТОРОЙ ПЕПЛОХОД

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 break down the information given in the question:

- The first ship sailed away from the dock at a speed of 18 km/h. - After 3 hours, the second ship sailed in the same direction and caught up with the first ship after 9 hours.

To calculate the speed of the second ship, we need to determine the distance traveled by both ships.

The distance traveled by the first ship can be calculated using the formula:

Distance = Speed × Time

For the first ship: - Speed = 18 km/h - Time = 3 hours

Using the formula, we can calculate the distance traveled by the first ship:

Distance of the first ship = 18 km/h × 3 hours = 54 km

Since the second ship caught up with the first ship after 9 hours, we can calculate the distance traveled by the second ship using the formula:

Distance of the second ship = Distance of the first ship

Distance of the second ship = 54 km

Now, we can calculate the speed of the second ship using the formula:

Speed of the second ship = Distance of the second ship / Time

For the second ship: - Distance = 54 km - Time = 9 hours

Using the formula, we can calculate the speed of the second ship:

Speed of the second ship = 54 km / 9 hours = 6 km/h

Therefore, the speed of the second ship is 6 km/h.
