Question

Из двух городов одновременно вышли навстречу друг другу два поезда один шёл мо скоростью 75км/ч, а другой со скоростью 85 км/ч, через 5 часов поезда встретились, определи расстояние между городам .

Answer 1

1) 75 + 85 = 160 (км) - проходят оба поезда за 1 час.

2) 160 × 5 = 800 (км) - прошли за 5 часов оба поезда.

Ответ: расстояние между городами равно 800 км.

Answer 2

Скорость сближения поездов  равна 75+85=160 км/ч
тогда расстояние  между городами 5*160=800 км/ч

Answer 3

Calculation of the Distance between the Cities

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

Distance = Speed x Time

Let's calculate the distance using the given information:

- Train 1 is traveling at a speed of 75 km/h. - Train 2 is traveling at a speed of 85 km/h. - The trains meet after 5 hours.

Using the formula, we can calculate the distance traveled by each train:

- Distance traveled by Train 1 = 75 km/h x 5 hours = 375 km - Distance traveled by Train 2 = 85 km/h x 5 hours = 425 km

To find the total distance between the cities, we can add the distances traveled by each train:

Total distance = Distance traveled by Train 1 + Distance traveled by Train 2

Total distance = 375 km + 425 km = 800 km

Therefore, the distance between the two cities is 800 kilometers.
