$\huge\boxed{\fcolorbox{white}{black}{answer☆}}$

1hours =60 minutes

3 hours = 60× 3 = 180 minutes

So, 180 minutes a car can cover distance = 150 km

1minute a car can cover distance = 150/ 180

12 minutes a car can cover distance= 150/ 180× 12 = 10 km

Therefore, a car can cover distance 12 minutes = 10km
