As the problem gave you the distance (d) and time (t), we use the relationship of distance, time, and speed (s):

s = d/t = 300/6 = 50 km/h

Now that the car covers 250kms, the time taken is (t=s/v (derived from v=s/t)):

250/50 = 5.

So the time taken by the car to travel 250kms is 5h.

I recommend that you check the units to make sure your answer is correct.
