Question

Total distance = 400 m
total time = 25s.
find Average speed.
​

Answer 1

Step-by-step explanation:

${\red{\underline{\underline{\bold{Given:-}}}}}$

• Total distance = 400m

• Total Time = 25 s

${\blue{\underline{\underline{\bold{To\:Find:-}}}}}$

• The Average Speed.

${\green{\underline{\underline{\bold{Solution:-}}}}}$

Formula used :-

$\boxed{Average\: Speed = \frac{Total\: Distance}{Total\:Time}}$

Substituting the values:-

$\bf \: Average \: speed = \frac{400}{25}$

$\bf \: Average \: speed = 8$

$\boxed{Average\: speed = 8m/s}$

Speed in km/hr

To convert speed from m/s to km/h multiply it with 18/5

$\bf \: = 8\times \frac{18}{5}$

$\bf\: = 28.8 km/hr$

Answer 2

Hi there!

Your Answer :- 8m/s.

$\tt\boxed{Given\ratio - }$

Total Distance = 400m

Total Time = 25s.

$\boxed{To \: \: find\ratio - }$

Average Speed.

$\boxed{Solution\ratio - }$

$\bf\red{Speed = \dfrac{Distance}{Time} }$

$\bf\blue{\dfrac{400}{25} = 8m {s}^{ - 1} }$
