Question

От Москвы до Ташкента 3375 км . Из этих городов одновременно вышли 2 поезда и встретились через 45 ч . Найди скорость московского поезда, если ташкентский проходит в среднем 132км за 4ч

Answer 1

132:4=33 км/ч скорость поезда из Ташкента
33+9=42 км/ч скор. поезда из Москвы
33*45+42*45=3375 км расстояние между м и т

132:4 = 33км/чскор поезда из Т
3375-33*45=1890 км расстояние, которое прош поезд из М
1890/45=42 км/ч скор поезда изМ

Answer 2

Calculating the Speed of the Moscow Train

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

Speed = Distance / Time

Given: - Distance from Moscow to Tashkent = 3375 km - Time taken for the trains to meet = 45 hours - Speed of the Tashkent train = 132 km/h

First, let's calculate the distance covered by the Moscow train when it met the Tashkent train.

Distance = Speed * Time

Distance = 132 km/h * 4 h

Distance = 528 km

Now, we can find the distance covered by the Moscow train:

Distance (Moscow train) = Total distance - Distance covered by Tashkent train

Distance (Moscow train) = 3375 km - 528 km

Distance (Moscow train) = 2847 km

Now, we can calculate the speed of the Moscow train:

Speed (Moscow train) = Distance (Moscow train) / Time

Speed (Moscow train) = 2847 km / 45 h

Speed (Moscow train) = 63.27 km/h

So, the speed of the Moscow train is approximately 63.27 km/h.
