Question

По арене цирка,диаметр которой 20 м,бегут лошади со скоростью 300 м/мин.сколько кругов пробегут лошади за 2 минуты? сколько прыжков выполнит кот-акробат за это же время,если за один круг он делает 26 прыжков? число п окружите до целых. ПОЖАЛУЙСТА

Answer 1

Ответ:

Пошаговое объяснение:

за 2 мин конь пробегает 300х2=600ма

длин круга 20х3,14=62,8м

количество кругов лошадь 600/62,88=9,55

кот пригнул 9,55х26=248

Answer 2

Calculation of Horse Laps:

To calculate the number of laps the horses will run in 2 minutes, we need to determine their speed in terms of laps per minute.

Given: - Diameter of the circus arena = 20 m - Horse speed = 300 m/min

To find the circumference of the circus arena, we can use the formula: Circumference = π * Diameter.

Let's calculate the circumference first:

Circumference = π * 20 m = 62.83 m

Now, we can calculate the number of laps the horses will run in 1 minute by dividing their speed by the circumference:

Laps per minute = Horse speed / Circumference = 300 m/min / 62.83 m = 4.77 laps/min

Finally, to find the number of laps the horses will run in 2 minutes, we multiply the laps per minute by 2:

Number of laps in 2 minutes = Laps per minute * 2 = 4.77 laps/min * 2 = 9.54 laps

Therefore, the horses will run approximately 9 laps in 2 minutes.

Calculation of Cat-Acrobat Jumps:

To calculate the number of jumps the cat-acrobat will perform in 2 minutes, we need to know how many jumps it makes per lap.

Given: - Number of jumps per lap = 26 jumps

To find the total number of jumps in 2 minutes, we need to multiply the number of jumps per lap by the number of laps the cat-acrobat completes in 2 minutes.

Using the previously calculated number of laps (9.54 laps), we can calculate the total number of jumps:

Total number of jumps = Number of jumps per lap * Number of laps in 2 minutes = 26 jumps * 9.54 laps = 248.04 jumps

Since we are asked to round to the nearest whole number, the cat-acrobat will perform approximately 248 jumps in 2 minutes.

Please note that these calculations are based on the given information and assumptions.
