Answer 2

${\huge{\boxed{\bf{\red{Answer}}}}}$

★ Lolly runs 30 km in 75 minutes .

Distance (Lolly) = 30 km

Time (Lolly) = 75 minutes = $\frac{75}{60}hours$ = 1.25 hours

so,

Speed of Lolly =

$= \frac{30}{1.25} = 24kmph$

★ Divya runs 12km in 40 minutes

Distance (Divya) = 12 km

Time (Divya) = 40 minutes = $\frac{40}{60}$=

$= \frac{2}{3} hours$

Speed of Divya =

$= \frac{12}{ \frac{2}{3} } = \frac{12 \times 3}{2} = 18kmph$

So, Clearly Lolly runs faster..

Formula used :

$speed \: = \frac{distance}{time}$
