Answer 1

${\huge{\underline{\pink{Answer :}}}}$

$\mathtt{\bf{\underline{\red{Given\: :}}}}$

Speed = 12 km.

Time = 20 minutes.

$\mathtt{\bf{\underline{\red{Formulas\: :}}}}$

Distance = Time × Speed.

Speed = Distance / Time.

$\mathtt{\bf{\underline{\red{According\:to\:the\:question\: :}}}}$

Distance = Time × Speed

Distance = 12 × 20 / 60

=> 4 km.

Speed = Distance / Time

So, 12 min = 4km / 12 m × 60.

=> 20 km.

Therefore, speed = 20 km.
