Question

Самолёт пролетает расстояние 2700км за 3 часа,а поезд проезжает расстояние в 6 раз меньше за час,что на 2 часа больший.Во сколько раз скорость самолёта больше скорости поезда

Answer 1

ОТМЕТЬ КАК ЛУЧШИЙ!
2700:3=900 км/ч - скорость самолета
900:6=150 км/ч - скорость поезда
900:150=6 раз
Ответ: 6 раз

Answer 2

Calculation of Speeds

To determine the ratio of the airplane's speed to the train's speed, we need to calculate the speeds of both the airplane and the train.

Given information: - The airplane travels a distance of 2700 km in 3 hours. - The train travels a distance that is 6 times smaller than the airplane's distance in 1 hour, and this distance is 2 hours less than the airplane's travel time.

Let's calculate the speeds of the airplane and the train:

1. Speed of the airplane: - Distance traveled by the airplane: 2700 km - Time taken by the airplane: 3 hours - Speed of the airplane = Distance / Time = 2700 km / 3 hours = 900 km/h.

2. Speed of the train: - Distance traveled by the train: 2700 km / 6 = 450 km - Time taken by the train: 3 hours - 2 hours = 1 hour - Speed of the train = Distance / Time = 450 km / 1 hour = 450 km/h.

Ratio of Speeds

Now, let's calculate the ratio of the airplane's speed to the train's speed:

- Ratio of speeds = Speed of the airplane / Speed of the train = 900 km/h / 450 km/h = 2.

Therefore, the speed of the airplane is 2 times greater than the speed of the train.
