Question

. Из Москвы в Санкт-Петербург, расстояние между которыми 650 км. выехал автобус со скоростью 70 км.час. Из Санкт-Петербурга в Москву одновременно отправился поезд со скоростью 60 км. час. Кто из них будет дальше от Москвы через 4 часа?

Answer 1

70*4=280 км
60*4=240 км
650-240=310 км ехать поезду до москвы, а автобус в 280 км

Answer 2

Calculation of Distance Traveled

To determine which mode of transportation will be farther from Moscow after 4 hours, we need to calculate the distance traveled by each vehicle.

The bus is traveling at a speed of 70 km/h, and the train is traveling at a speed of 60 km/h. Since both vehicles started at the same time, we can calculate the distance traveled by each vehicle using the formula:

Distance = Speed x Time

For the bus: Distance traveled by the bus = 70 km/h x 4 hours

For the train: Distance traveled by the train = 60 km/h x 4 hours

Let's calculate the distances:

Distance traveled by the bus = 70 km/h x 4 hours = 280 km.

Distance traveled by the train = 60 km/h x 4 hours = 240 km.

Comparison of Distances

After 4 hours, the bus will be 280 km away from Moscow, and the train will be 240 km away from Moscow. Therefore, the bus will be farther from Moscow.

Please note that these calculations assume constant speeds and no stops or delays during the journey.
