MARK ME HAS BRAINLIEST

Explanation:

As given in question that

Distance = 20 km

Time = 20 min =(20/60)hr=1/3hr

So according to formula i.e

Distance(d) = speed(v) × time(t)

So v= d/t=20×3/1=60 km/hr

So if car travel need to travel 20 km in 20 min i.e 1/3 hr so it must be move with speed 60 km/hr.
