Question

По просёлочной дороге едет-мчится Дед Мороз. Он проехал 2400 м за 4 мин. По этой дороге можно двигаться со скоростью не более 40км/ч. Нарушил ли Дед Мороз скоростной режим просёлочной дороги?

Answer 1

В одном километре 1000 метров, значит он проехал 2,4 км.в одном часе 60 мину, значит 4 минуту это 4/60 =2/30=1/15посчитаем скорость v=s/t v=2,4:1/15 12/5*15=36 км/ч - значит не нарушил)))

Answer 2

40км/ч=40.000 м/60 мин
40000:60*4~2666,67

Answer 3

Did Ded Moroz violate the speed limit on the dirt road?

Ded Moroz traveled a distance of 2400 meters in 4 minutes on the dirt road. To determine if he violated the speed limit, we need to convert the given speed limit of 40 km/h to meters per minute.

To convert km/h to meters per minute, we can use the following conversion factor: 1 km = 1000 meters 1 hour = 60 minutes

Therefore, 40 km/h can be converted to meters per minute as follows: 40 km/h * (1000 meters / 1 km) * (1 hour / 60 minutes) = 40,000 meters / 60 minutes = 666.67 meters per minute.

Since Ded Moroz traveled 2400 meters in 4 minutes, we can calculate his average speed as follows: 2400 meters / 4 minutes = 600 meters per minute.

Comparing Ded Moroz's average speed of 600 meters per minute to the speed limit of 666.67 meters per minute, we can conclude that Ded Moroz did not violate the speed limit on the dirt road.
