Question

Со станции одновременно в противоположных направлениях отправились 2 поезда. Один поезд ехал со скоростью 72 км/ч, а другой 70 км/ч. Какое расстояние было между ними когда второй поезд проехал 210 км.

Answer 1

210/70=3 часа ехал второй поезд

3*72=216 км проехал первый поезд

210+216=426 км расстояние м/д поездами

 

 

 

 

Answer 2

Calculation of the Distance between the Trains

To calculate the distance between the two trains, we can use the formula:

Distance = Speed × Time

Let's calculate the time it takes for the second train to travel 210 km at a speed of 70 km/h:

Time = Distance / Speed = 210 km / 70 km/h = 3 hours

Now that we know the time it took for the second train to travel 210 km, we can calculate the distance between the two trains when the second train completed its journey.

The first train was traveling at a speed of 72 km/h, so in 3 hours, it would have traveled:

Distance = Speed × Time = 72 km/h × 3 hours = 216 km

Therefore, when the second train completed its journey of 210 km, the distance between the two trains was 216 km.

Please note that the above calculations are based on the given speeds and distances provided in the question.
