Question

Пирамида фараона джосера имеет прямоугольное основание она занимает площадь 12500метров в квадрате,скорость пешехода 30 метров в минуту сколько времени нужно чтобы обойти эту пирамиду если одна её сторона равна 100 м?

Answer 1

S основ.=a*b12500=a*100a=125 м длина второй стороны основаниянаходим периметр основания P=2(a+b)P=(100+125)*2=450 м находим время в пути t=S/v; t=450/30=15 мин 

Answer 2

12500/100=125м вторая сторона
125+125+100+100=450м перметр или длина всех сторон
450/30=15мин

Answer 3

Calculating the Time to Walk Around the Pyramid of Pharaoh Djoser

To calculate the time needed to walk around the pyramid of Pharaoh Djoser, we can use the given information about the pyramid's dimensions and the pedestrian's walking speed.

Given: - Area of the pyramid's base: 12500 square meters - Walking speed: 30 meters per minute - Length of one side of the pyramid: 100 meters

Calculations:

To find the perimeter of the pyramid's base, we can use the formula for the perimeter of a rectangle, where the perimeter (P) is given by: \[ P = 2 \times (length + width) \]

Given that the length and width of the pyramid's base are both 100 meters, the perimeter is: \[ P = 2 \times (100 + 100) = 2 \times 200 = 400 \text{ meters} \]

Now, to find the time needed to walk around the pyramid, we can use the formula: \[ \text{Time} = \frac{\text{Distance}}{\text{Speed}} \]

Given that the distance to walk around the pyramid is equal to its perimeter, which is 400 meters, and the walking speed is 30 meters per minute, the time needed to walk around the pyramid is: \[ \text{Time} = \frac{400 \text{ meters}}{30 \text{ meters/minute}} \]

Result:

\[ \text{Time} = \frac{400}{30} = 13.33 \text{ minutes} \]

So, it would take approximately 13.33 minutes to walk around the pyramid of Pharaoh Djoser at a speed of 30 meters per minute.
