Question

Теплоход проходит за 4ч. такое же расстояние,как и моторная лодка за 9ч.Узнай скорость моторной лодки,если известно,что скорость теплохода 36 км\ч.

Answer 1

1) 36*4=144 (км) проходит теплоход за 4 часа
тоже самое расстояние проходит и лодка за 9 часов, следовательно
2) 144/9=16 (км/ч) скорость лодки
ответ: 16 км/ч скорость лодки

Answer 2

Problem Analysis

We are given that a steamboat travels a certain distance in 4 hours, and a motorboat travels the same distance in 9 hours. We need to find the speed of the motorboat, given that the speed of the steamboat is 36 km/h.

Solution

Let's assume the distance traveled by both the steamboat and the motorboat is d.

We can use the formula speed = distance / time to find the speed of the motorboat.

The speed of the steamboat is given as 36 km/h, and the time taken by the steamboat is 4 hours. Therefore, we can calculate the distance d as follows:

d = speed * time = 36 km/h * 4 hours = 144 km.

Now, we can use the distance d and the time taken by the motorboat (9 hours) to find its speed:

speed of motorboat = distance / time = 144 km / 9 hours = 16 km/h.

Therefore, the speed of the motorboat is 16 km/h.

Answer

The speed of the motorboat is 16 km/h.
