Explanation


The average speed of the vehicle is calculated by dividing the distance traveled by the time taken. 

The distance traveled is given as 2xy km, and the time taken is given as x+y hours.

Therefore, the average speed is 2xy km / (x+y) hours.

The distance traveled in 5 hours and 48 minutes is calculated by multiplying the average speed by the time taken. 

The average speed is given as 200/29 km/hr and the time taken is given as 5 hours and 48 minutes, 

which is equivalent to 29/5 hours. 

Therefore, the distance traveled is (200/29 km/hr) * (29/5 hours) = 40 km.

The distance of the post office from the village is calculated by dividing the distance traveled by 2, 

since the vehicle traveled to the post office and back. 

In this case, the distance traveled was 40 km, 

so the distance of the post office from the village is 40 km / 2 = 20 km.
