Question

от станции в противоположных направлениях одновременно отошли 2 поезда. скорость 1 поезда 90 км/ч 2- на 5 км/ч больше. какое расстояние будет между поездами через 3 часа

Answer 1

1).90*3=270
2). 90+5=95
3). 95*3=285

Answer 2

1)90+5=95 км/ч скорость второго поезда
2)90+95=185 км/ч общая скорость поездов
3)185*3=555 км/ч расстояние между поездами

Answer 3

Calculation of the Distance Between Two Trains

To calculate the distance between two trains that departed from opposite directions simultaneously, we need to consider the speeds of the trains and the time that has passed.

Given information: - Speed of the first train: 90 km/h - Speed of the second train: 95 km/h (5 km/h faster than the first train) - Time elapsed: 3 hours

To find the distance between the two trains after 3 hours, we can use the formula:

Distance = Speed × Time

Let's calculate the distance for each train and then find the total distance between them.

For the first train: Distance of the first train = 90 km/h × 3 hours = 270 km

For the second train: Distance of the second train = 95 km/h × 3 hours = 285 km

To find the total distance between the two trains, we can add the distances of each train:

Total distance = Distance of the first train + Distance of the second train Total distance = 270 km + 285 km = 555 km

Therefore, the distance between the two trains after 3 hours is 555 km.
