Chapter 4, Problem 26A

Calculate your average walking speed when you step 1 meter in 0.5 second.

To determine

Average walking speed.

Answer to Problem 26A

Average walking speed is, $v=2\text{ m/s}$

Explanation of Solution

Given :

Distance covered in one step, $s=1\text{ m}$

Time taken to cover 1 step is, $t=0.5\text{ s}$

Formula used :

The speed is,

  $s=vt$

Where, s is distance traveled, v is speed and t is time.

Calculation :

Substituting the value of s and t and solve.

  $\begin{array}{l}1=v\times 0.5\\ v=\frac{1}{0.5}\\ =2\text{ m/s}\end{array}$

Conclusion :

Therefore, average walking speed is 2 m/s.
