Question

Первый поезд вышел 70 км в час.через 2 часа вышел второй поезд 90 км в час. какое расстояние будет через 3 часа между поездами

Answer 1

1)70*5=350(км)-проехал поезд со скоростью 70км.ч 2)90*3=270(км)-проехал поезд со скоростью 90км.ч 3)350-270=80(км)- растояние между поездами.

Answer 2

Calculating the Distance Between Two Trains

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

Distance = Speed × Time

Given: - The first train travels at a speed of 70 km/h. - The second train travels at a speed of 90 km/h. - Both trains have been traveling for 3 hours.

Calculating the Distance Traveled by Each Train

First, let's calculate the distance each train has traveled in 3 hours.

The distance traveled by the first train: Distance = Speed × Time Distance = 70 km/h × 3 h = 210 km The distance traveled by the second train: Distance = Speed × Time Distance = 90 km/h × 3 h = 270 km

Calculating the Distance Between the Trains

Now, to find the distance between the two trains after 3 hours, we can subtract the distance traveled by the first train from the distance traveled by the second train.

Distance between the trains = Distance traveled by the second train - Distance traveled by the first train Distance between the trains = 270 km - 210 km = 60 km

So, after 3 hours, the distance between the two trains will be 60 kilometers.
