Question

kabir takes 50 seconds to run one round of his school ground of path 200m. Calculate his speed.​

Answer 1

Step-by-step explanation:

speed is distance upon time

200/50=4 m/s

Answer 2

Kabir's speed is 4 m/s.

Tips:

Speed is defined by the distance travelled in unit time. That is, if d be the distance travelled in time t, then the speed s is given by

$\quad s=\dfrac{d}{t}=dt^{-1}$

Step-by-step explanation:

Given, Kabir takes 50 seconds to run one round of his screen group of path 200 meters. So, we can write:

• d = 200 meters
• t = 50 seconds

Then Kabir's speed is

$\quad s=\dfrac{d}{t}=\dfrac{200}{50}\:m/s=4\:m/s$

Extra:

We can use the formula $s=\dfrac{d}{t}$ to find any one of the three, when two of them is given.

Just make sure to write down the units correctly.
