Answer 2

$\sf\huge\bold{Answer:}$

Given :

80m/s

To find :

Value of 80m/s in km/h

Solution :

$\tt\ = \frac{80m}{1s}$

$\tt\red{1m = 1000km}$

$\tt\red{1s= 60min = 60 \times 60hrs \: i.e \: 3600hrs}$

$\tt\ = \frac{(80 \times 1000)km}{(1 \times 3600)hr}$

$\tt\ = \frac{80000km}{3600hr}$

${=}$$\displaystyle{\tt { \cancel{ \frac{80000km}{3600hr} }}}$

$\tt\ = \frac{200km}{9hr}$

${=}$$\displaystyle{\tt { \cancel{ \frac{200km}{9hr} }}}$

$\tt\ = 22.222...km/h$

$\tt\purple{ 30m/s ≈ 22.3km/h}$
