Question

Из Москвы и Саратова вышли одновременно навстречу друг другу два поезда. Скорость первого поезда 62 км/час а второго 74 км/час. На каком расстоянии друг от друга будут находиться поезда через 9 часов после начала движения если от Москвы до Саратова 892 км?

Answer 1

1) 62 * 5 = 310 (км) - пройдет 1 поезд за 5 часов 
2) 74 * 5 = 370 (км) - пройдет 2 поезд за 5 часов 
3) 310 + 370 = 680 (км) - пройдут вместе за 5 часов 
4) 892 - 680 = 212 (км) 
Ответ: на расстояние 212 км. 

Answer 2

Problem Analysis

We are given that two trains start simultaneously from Moscow and Saratov and are moving towards each other. The speed of the first train is 62 km/h, and the speed of the second train is 74 km/h. We need to find the distance between the two trains after 9 hours of travel.

Solution

To find the distance between the two trains after 9 hours, we can use the formula:

Distance = Speed x Time

Let's calculate the distance traveled by each train after 9 hours and then find the total distance between them.

The first train travels at a speed of 62 km/h for 9 hours, so the distance traveled by the first train is:

Distance of the first train = Speed of the first train x Time = 62 km/h x 9 hours

The second train travels at a speed of 74 km/h for 9 hours, so the distance traveled by the second train is:

Distance of the second train = Speed of the second train x Time = 74 km/h x 9 hours

To find the total distance between the two trains, we need to add the distances traveled by each train:

Total distance = Distance of the first train + Distance of the second train

Let's calculate the distances and find the total distance.

Calculation

Distance of the first train = 62 km/h x 9 hours = 558 km

Distance of the second train = 74 km/h x 9 hours = 666 km

Total distance = 558 km + 666 km = 1224 km

Answer

The two trains will be 1224 km apart from each other after 9 hours of travel.
