Question

Поезд идет со скоростью 72км\ч. выразите его скорость в метрах в секундах

Answer 1

72 км/ч = 72*1000\3600= 20 м/с

Answer 2

Calculation of Speed in Meters per Second

To convert the speed of a train from kilometers per hour (km/h) to meters per second (m/s), we need to multiply the speed in km/h by 1000/3600. This conversion factor accounts for the fact that there are 1000 meters in a kilometer and 3600 seconds in an hour.

Given that the train is traveling at a speed of 72 km/h, we can calculate its speed in m/s as follows:

Speed in m/s = (72 km/h) * (1000 m/km) / (3600 s/h)

Let's perform the calculation:

Speed in m/s = (72 * 1000) / 3600

Using a calculator, we find that the speed of the train is approximately 20 m/s.
