Question

Взрослый человек при ходьбе делает за 3 минуты 360 шагов длиной по 75 см..,а при беге наибольшая скорость его 10 м/c.На склдько метров при беге человек передвигается больше,чем при ходьбе,1 сек.? за 1 мин.?

Answer 1

360:3=120 шагов за минуту
120:60 =2 шага за секунду, значит 2*75=150 см=1,5м
10м-1,5м=8,5метров
120* 75=9000см=90м
10*60=600м
600м -90м =510метров

Answer 2

Calculation of Distance Covered in 1 Second

To calculate the distance covered in 1 second during walking and running, we need to consider the number of steps taken and the length of each step.

For walking: - The person takes 360 steps in 3 minutes. - Each step is 75 cm long.

To find the distance covered in 1 second during walking, we can use the following formula:

Distance covered in 1 second (walking) = (Number of steps * Length of each step) / Time in seconds

Substituting the given values: - Number of steps = 360 - Length of each step = 75 cm - Time in seconds = 3 minutes * 60 seconds/minute = 180 seconds

Distance covered in 1 second (walking) = (360 * 75) / 180 = 150 cm

For running: - The person's maximum speed is 10 m/s.

To find the distance covered in 1 second during running, we can use the following formula:

Distance covered in 1 second (running) = Speed * Time in seconds

Substituting the given values: - Speed = 10 m/s - Time in seconds = 1 second

Distance covered in 1 second (running) = 10 m

Comparison of Distance Covered in 1 Minute

To compare the distance covered in 1 minute during walking and running, we need to convert the distance covered in 1 second to the distance covered in 1 minute.

For walking: - Distance covered in 1 second = 150 cm

To find the distance covered in 1 minute during walking, we can use the following formula:

Distance covered in 1 minute (walking) = Distance covered in 1 second * 60 seconds

Substituting the given value: - Distance covered in 1 second = 150 cm

Distance covered in 1 minute (walking) = 150 cm * 60 = 9000 cm

For running: - Distance covered in 1 second = 10 m

To find the distance covered in 1 minute during running, we can use the following formula:

Distance covered in 1 minute (running) = Distance covered in 1 second * 60 seconds

Substituting the given value: - Distance covered in 1 second = 10 m

Distance covered in 1 minute (running) = 10 m * 60 = 600 m

Therefore, a person covers 9000 cm (or 90 meters) more distance in 1 minute while running compared to walking for 1 second.
