Answer 2

Given:

Distance walked by Lauren = 100 m

Time taken = half minute

To find:

The speed of Lauren.

Solution:

We know that speed can be found out by dividing the distance traveled by the time taken to travel that particular distance. Thus, the formula of speed is:

Speed = Distance/ Time

On substituting the values in the given formula, we get:

$= \frac{100 m}{0.5 min}$

Now, we will convert minutes into seconds:

$= \frac{100 m}{30sec}$

= 3.33 m/s

Thus the speed of Lauren is 3.33 m/s.
