Answer 2

Answer:

Speed = 6 km/hr

Step-by-step explanation:

Distance = 3 km

Time = 30 min

1 min = $\frac{1}{60}$ hr

30 min = $\frac{30}{60}$ = $\frac{1}{2}$ hr

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

           ⇒ $\frac{3km}{\frac{1}{2}hr }$

           ⇒ $\frac{3 * 2 km}{1 hr }$

           ⇒ 6 km/hr
