Two girls move in opposite directions, one from A to B and other from B to A. The girl from A reaches the destination in 16 hrs and girl from B reaches her destination in 25 hrs, after having met. If former's speed is 25 km/hr, what will be the speed of latter?  Choose the most appropriate option
A) 10 km/hr B) 12 km/hr C) 16 km/hr D) 20 km/hr E) 25 km/hr
Hint: If two bodies A and B move from each other's starting point in opposite directions, they reach their destinations after having met, then their speeds Sa &amp; Sb are given by,   Sa	/ Sb = √tb / √ta   where t is the time taken by them to cover the distance.   Sb	(25 x 4)	/ 5 = 20 km/hr   ANSWER IS 20 km/hr
