Question

Человек делает 15 шагов за 9с. Длина каждого шага составляет 75см. Сколько времени потратит человек на преодоление 1км пути?

Answer 1

8 минут
1000/((15*75)/9)=8

Answer 2

Calculating Time to Cover 1km

To calculate the time it takes for a person to cover 1km, we can use the given information about the number of steps taken in a certain time period and the length of each step.

Given: - Number of steps in 9 seconds: 15 steps - Length of each step: 75cm

First, let's calculate the total distance covered in 15 steps: - Total distance covered in 15 steps = 15 steps * 75cm/step

Next, we'll convert the total distance to kilometers: - Total distance in kilometers = (Total distance in cm) / 100,000 (since 1km = 100,000cm)

Then, we'll calculate the time it takes to cover 1km based on the given information.

Let's proceed with the calculations.

Calculation

Total distance covered in 15 steps: - Total distance = 15 steps * 75cm/step = 1125cm

Converting total distance to kilometers: - Total distance in kilometers = 1125cm / 100,000 = 0.01125km

Now, we need to calculate the time it takes to cover 1km based on the given information.

Time Calculation

Using the given information: - Number of steps in 9 seconds: 15 steps

We can calculate the time it takes to cover 1km: - Time to cover 1km = (9 seconds / 15 steps) * (100,000cm / 1125cm)

Let's calculate the time it takes to cover 1km based on the given information.

Result

The time it takes for the person to cover 1km is approximately 60 seconds.

This calculation is based on the given number of steps taken in 9 seconds and the length of each step.
