Question

Из Москвы И Саратова вышли одновременно навстречу друг другу два поезда. Скорость одного поезда 62 км/ч а другого 74 км/ч. На каком расстоянии друг от друга будут находиться поезда через 4 ч после начала движения если от Москвы да Саратова 892 км ?

Answer 1

892-(62+74)*4=348км правильный ответ

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 one train is 62 km/h, and the speed of the other train is 74 km/h. We need to find the distance between the trains after 4 hours of travel.

Calculation

To find the distance between the trains after 4 hours, we can use the formula:

Distance = Speed × Time

Let's calculate the distance traveled by each train after 4 hours.

The first train's speed is 62 km/h, so the distance traveled by the first train after 4 hours is:

Distance of the first train = 62 km/h × 4 h = 248 km

The second train's speed is 74 km/h, so the distance traveled by the second train after 4 hours is:

Distance of the second train = 74 km/h × 4 h = 296 km

Since the trains are moving towards each other, the distance between them is the sum of the distances traveled by each train:

Total distance between the trains = Distance of the first train + Distance of the second train = 248 km + 296 km = 544 km

Therefore, the trains will be 544 km apart after 4 hours of travel.

Answer

The trains will be 544 km apart from each other after 4 hours of travel.
