Question

Мальчик,поднимающийся в лифте,следит за показаниями электронного табло.Он замечает,что за 12с лифт поднялся от 2-го до 12-го этажа.Сколько времени займет подъем от 12-го до 27-го этажа?лифт движется равномерно

Answer 1

Вычислим, за какое время лифт поднимается на 1 этаж:

12с/10 эт = 1,2 с.

 

Дальше, определим, сколько этажей стоит еще проехать:

27 эт. - 12 эт. = 15 эт.

 

И теперь вычислим время, за которое лифт поднимется с 12 до 27 этажа:

1,2*15 = 18 с.

 

Ответ: 18 с.

Answer 2

Calculation of Time for Elevator Ride

To calculate the time it will take for the elevator to travel from the 12th floor to the 27th floor, we need to determine the time it takes for the elevator to travel one floor.

Given that the elevator traveled from the 2nd floor to the 12th floor in 12 seconds, we can calculate the time it takes for the elevator to travel one floor by dividing the total time by the number of floors traveled.

Let's calculate the time it takes for the elevator to travel one floor:

Time to travel one floor = Total time / Number of floors traveled

Time to travel one floor = 12 seconds / (12 - 2) floors

Time to travel one floor = 1 second per floor

Since the elevator moves at a constant speed, we can assume that it will take 1 second to travel from the 12th floor to the 13th floor, from the 13th floor to the 14th floor, and so on.

To calculate the total time it will take for the elevator to travel from the 12th floor to the 27th floor, we need to subtract the starting floor (12th floor) from the destination floor (27th floor) and multiply it by the time it takes to travel one floor.

Total time = (Destination floor - Starting floor) * Time to travel one floor

Total time = (27 - 12) floors * 1 second per floor

Total time = 15 seconds

Therefore, it will take the elevator approximately 15 seconds to travel from the 12th floor to the 27th floor.
