Question

Расстояние от Москвы до Новосибирска 3320 км. Самолет пролетает его за 4ч. За какое время проедет это расстояние поезд,если скорость поезда в 10 раз меньше скорости самолета?На сколько быстрее лететь до Новосибирска самолетом,чем ехать на поезде?

Answer 1

Calculation of Train Travel Time

To calculate the time it takes for a train to travel from Moscow to Novosibirsk, we need to consider the distance between the two cities and the speed of the train.

Given: - Distance from Moscow to Novosibirsk: 3320 km - Flight time from Moscow to Novosibirsk: 4 hours - Train speed is 10 times slower than the speed of the plane

To find the time it takes for the train to travel the distance, we can use the formula:

Time = Distance / Speed

Let's calculate the train travel time:

Train speed = 1/10 * Plane speed

Train travel time = Distance / Train speed

Train travel time = 3320 km / (1/10 * Plane speed)

Train travel time = 3320 km / (1/10 * 4 hours)

Train travel time = 3320 km / (0.1 * 4 hours)

Train travel time = 3320 km / 0.4 hours

Train travel time = 8300 hours

Therefore, it would take approximately 8300 hours for the train to travel from Moscow to Novosibirsk.

Comparison of Plane and Train Travel Times

To determine how much faster it is to fly to Novosibirsk compared to traveling by train, we can compare the travel times of both modes of transportation.

- Plane travel time: 4 hours - Train travel time: 8300 hours

To find the difference in travel times, we can subtract the train travel time from the plane travel time:

Difference in travel times = Plane travel time - Train travel time

Difference in travel times = 4 hours - 8300 hours

Difference in travel times = -8296 hours

The negative value indicates that the train travel time is significantly longer than the plane travel time. The plane is much faster compared to the train for traveling from Moscow to Novosibirsk.

Please note that the calculated train travel time is an approximation and may vary depending on the specific train schedule and speed.
