Question

Расстояние между двумя городами ,равное 440 км .поезд прошёл за 8ч.Первые 4 чон ехал со скоростью 50км\ч .С какой скоростью поезд прошел остаток пути?ПОМОГИТЕ ПОЖАЛУЙСТА))))

Answer 1

4 * 50 = 200 ( км ) проехал первые четыре часа 
440 - 200 = 240 ( км ) проехал вторые четыре часа 
240 : 4 = 60 ( км/час ) скорость на остатке пути
Ответ 60 км/час 

Answer 2

Calculation of the Remaining Distance

To calculate the speed at which the train traveled the remaining distance, we can use the formula:

Speed = Distance / Time

Given that the total distance between the two cities is 440 km and the train took 8 hours to cover this distance, we can calculate the speed at which the train traveled the first 4 hours:

Speed = Distance / Time = 440 km / 8 hours = 55 km/h.

Since the train traveled the first 4 hours at a speed of 50 km/h, we can calculate the distance covered during this time:

Distance = Speed x Time = 50 km/h x 4 hours = 200 km.

Therefore, the remaining distance is:

Remaining Distance = Total Distance - Distance Covered = 440 km - 200 km = 240 km.

Calculation of the Speed for the Remaining Distance

To calculate the speed at which the train traveled the remaining distance of 240 km, we can use the same formula:

Speed = Distance / Time.

In this case, the distance is 240 km and the time is the remaining time after the first 4 hours, which is 8 hours - 4 hours = 4 hours.

Speed = 240 km / 4 hours = 60 km/h.

Therefore, the train traveled the remaining distance of 240 km at a speed of 60 km/h.
