Question

Длина участка железнодорожной магистрали на карте, составленной в масштабе 1:6 000 000, равна18см. За какое время продет поезд данный участок железнодорожной магистрали со скоростью 75км/ч?

Answer 1

18*6000000=108000000 см = 1080 км
1080 : 75 = 14,4 часа = 14 часов 24 минуты 

Answer 2

Calculating Train Travel Time on a Map

To calculate the time it takes for a train to travel a certain distance at a given speed, we can use the formula:

Time = Distance / Speed

First, let's convert the given speed from kilometers per hour (km/h) to centimeters per minute (cm/min) to match the scale of the map.

1 kilometer = 100,000 centimeters 1 hour = 60 minutes

So, 75 km/h = (75 * 100,000) / 60 cm/min = 125,000 cm/min

Now, we can calculate the time it takes for the train to travel the given distance on the map.

Distance on the map: 18 cm Speed: 125,000 cm/min

Using the formula: Time = Distance / Speed

Time = 18 cm / 125,000 cm/min

Calculating: Time ≈ 0.000144 minutes

So, the train would take approximately 0.000144 minutes to travel the given distance at a speed of 75 km/h.
