Answer 1

$\huge\star{\tt{\boxed{\underline{\red{\mid{Answer \implies 0.125km/hr }}}}}}\star$

$\huge\star{\mathfrak{\underline{\blue{Explanation:}}}}$

_________________________________

Distance=25m

$\implies$$\large\frac{25}{1000}$

$\bigcirc$0.025km

Time=12 seconds

$\implies$$\frac{12}{60}$

T=0.2 hour

_________________________

$\blacksquare$Speed=$\frac{Distance}{Time}$

Speed=$\frac{0.025}{0.2}$

$\bigcirc$0.125km/hr
