Answer 1

9х40=360
360:6=60 
Ответ: скорость пассажирского поезда 60 км/ч

Answer 2

Problem Analysis

We are given that a freight train traveled from one station to another in 9 hours, and a passenger train traveled the same distance in 6 hours. We need to find the speed of the passenger train, given that the speed of the freight train is 40 km/h.

Solution

To find the speed of the passenger train, we can use the formula:

Speed = Distance / Time

Since both trains traveled the same distance, we can set up the following equation:

40 km/h = Distance / 9 hours

Solving for the distance, we get:

Distance = 40 km/h * 9 hours

Now, we can use the distance and the time taken by the passenger train to find its speed:

Speed of passenger train = Distance / 6 hours

Let's calculate the speed of the passenger train:

Calculation

Distance = 40 km/h * 9 hours = 360 km

Speed of passenger train = 360 km / 6 hours = 60 km/h

Therefore, the speed of the passenger train is 60 km/h.

Answer

The speed of the passenger train is 60 km/h.
