Answer 1

1) 3 375 : 45 = 75 (км/ч) - средняя скорость

2) 132 : 4 =33 (км/ч) -скорость Ташкентского поезда

3) 75 - 33 =42 (км/ч) - скорость Московского поезда

Answer 2

Problem Analysis

We are given that the distance between Moscow and Tashkent is 3375 km. Trains from both cities start simultaneously and meet after 45 hours. We are also given that the train from Tashkent travels an average of 132 km in 4 hours. We need to find the speed of the train from Moscow.

Solution

Let's assume the speed of the train from Moscow is x km/h. Since both trains travel for the same amount of time and meet at a certain point, we can set up the following equation:

Distance traveled by the Moscow train = Distance traveled by the Tashkent train

The distance traveled by the Moscow train can be calculated using the formula: distance = speed × time.

For the Moscow train: Distance = x km/h × 45 hours

For the Tashkent train: Distance = 132 km/h × 4 hours

Setting these two distances equal to each other, we can solve for x:

x × 45 = 132 × 4

Simplifying the equation:

45x = 528

Dividing both sides by 45:

x = 528 / 45

Evaluating the expression:

x ≈ 11.733 km/h

Therefore, the speed of the Moscow train is approximately 11.733 km/h.

Answer

The speed of the Moscow train is approximately 11.733 km/h.
