Answer:

5 km/hr

Step-by-step explanation:

Two-thirds of the distance means: (2/3)*6 km =4 km

The time take two-thirds of the distance at 4 km/hr is = (4/4) hr = 1 hr

= 60 minutes

Now, the time left to cover the rest distance( 6 - 4 = 2km ) is 84 - 60 minutes = 24 minutes

24 min to cover distance 2 km

1 ---------------------------          2/24 km

60--------------------------         (2/24) * 60 km    

                                            = 5 km

So, the speed required to cover the distance is 5 km/hr.
