Question

Расстояние между двумя городами 240 км половину пути электричка идёт без остановок остальной путь она проходит за 3ч вычисли скорость электрички на втором участке пути?

Answer 1

1) 240:2=120км/ч.
2) 120:3=40км/ч.
Ответ: 40 км/ч.

Answer 2

240 км это весь путь
240÷2=120 км половина пути или остальной путь
120÷3=40 км скорость на 2 участке пути

Answer 3

Calculation of the Train Speed on the Second Leg of the Journey

To calculate the speed of the train on the second leg of the journey, we need to determine the time it takes for the train to cover the remaining distance after the non-stop portion.

Given: - Total distance between the two cities: 240 km - The train covers half of the distance without any stops - The remaining distance is covered in 3 hours

To find the speed of the train on the second leg, we can use the formula:

Speed = Distance / Time

Let's calculate the distance covered during the non-stop portion of the journey:

Distance covered in the non-stop portion = Total distance / 2 = 240 km / 2 = 120 km

Now, we can calculate the speed on the second leg:

Speed = Remaining distance / Time

Speed = (Total distance - Distance covered in the non-stop portion) / Time

Speed = (240 km - 120 km) / 3 hours

Speed = 120 km / 3 hours

Speed = 40 km/h

Therefore, the speed of the train on the second leg of the journey is 40 km/h.
