Question

Скорость пассажирского поезда 90 км/ч,а скорость товарного-60 км/ч. Какую часть скорости пассажирского поезда составляет скорость товарного поезда?Во сколько раз скорость пассажирского поезда больше скорости товарного?

Answer 1

1. задача
1) 60 : 90 = 60/90 =  2/3 часть скорости пассажирского поезда составляет скорость товарного поезда
2) 90 : 60 = 1,5 = 1 1/2 раза скорость пассажиропотока поезда больше скорости товарного

Answer 2

Calculation of the Proportion and Ratio of Speeds

To calculate the proportion of the speed of the passenger train to the speed of the freight train, we can use the formula:

Proportion = Speed of Passenger Train / Speed of Freight Train

Given that the speed of the passenger train is 90 km/h and the speed of the freight train is 60 km/h, we can substitute these values into the formula:

Proportion = 90 km/h / 60 km/h

Simplifying the expression, we get:

Proportion = 1.5

This means that the speed of the passenger train is 1.5 times the speed of the freight train.

To calculate the ratio of the speed of the passenger train to the speed of the freight train, we can use the formula:

Ratio = Speed of Passenger Train : Speed of Freight Train

Substituting the values, we get:

Ratio = 90 km/h : 60 km/h

Simplifying the expression, we get:

Ratio = 3 : 2

This means that the speed of the passenger train is 3 times the speed of the freight train.

Therefore, the proportion of the speed of the passenger train to the speed of the freight train is 1.5, and the speed of the passenger train is 3 times the speed of the freight train.
