Question

Скорый поезд проехал расстояние 3750 км за 15 часов,а другой 5880 за 21 час. скорость какого поезда больше и насколько?

Answer 1

Скорость=путь/время 1) 3750/15=250км/час 2)5880/21=280км/час Ответ: 250 км/час, 280 км/час; скорость второго поезда больше первого на 30 км/час

Answer 2

Speed of Trains

To find the speed of each train, we can use the formula:

Speed = Distance / Time

For the first train: - Distance = 3750 km - Time = 15 hours

For the second train: - Distance = 5880 km - Time = 21 hours

Let's calculate the speeds of the two trains.

Calculating Speeds

For the first train: - Speed = 3750 km / 15 hours = 250 km/h For the second train: - Speed = 5880 km / 21 hours = 280 km/h

Conclusion

Therefore, the speed of the second train is greater than the speed of the first train by 30 km/h.
