Answer 1

Question -

An athelete runs 200 metres race in 24 seconds. His speed in km/hr is

Answer

We know,

• $\boxed{\sf Speed = \frac{Distance}{Time}}$

$\sf Speed = \frac{\cancel {200}}{\cancel {24}} = \frac{25}{3} m/s$

• To convert m/s to km/hr multiply by 18/5

$\sf \frac{25}{3} m/s = \frac{\cancel {25}}{\cancel {3}} \times \frac{\cancel {18}}{ \cancel {5}} km/hr$

$\sf = 5 \times 6$

$\sf = 30 km/hr$

Answer 2

$\huge\mathcal\red{Answer:-}$

$\implies$Speed = 200/24

$\implies$In Km/hr = 200/24 x 18/5 => 30 Km/hr
