Question

первый поезд проехал 251,6км за 4ч,второй поезд-298км за 5 км.Найдите скорости поездов,сравните их

Answer 1

V = S/t
V первого поезда = 251.6км : 4ч = 62.9 км/ч
V второго поезда = 298км : 5ч = 59.6 км/ч
62.9 км/ч > 59.6 км/ч =>  первый поезд быстрее.
Ответ: скорость первого поезда = 62.9 км/ч
           скорость второго поезда = 59.6 км/ч
           62.9 км/ч > 59.6 км/ч

Answer 2

Calculating Train Speeds and Comparison

To find the speeds of the trains, we can use the formula:

Speed = Distance / Time

For the first train: - Distance = 251.6 km - Time = 4 hours

For the second train: - Distance = 298 km - Time = 5 hours

Let's calculate the speeds of the trains.

For the first train: - Speed = 251.6 km / 4 hours = 62.9 km/h

For the second train: - Speed = 298 km / 5 hours = 59.6 km/h

Comparison of Train Speeds

Comparing the speeds of the two trains: - The first train has a speed of 62.9 km/h. - The second train has a speed of 59.6 km/h.

Therefore, the first train is traveling at a higher speed compared to the second train.
