Two buses started simultaneously towards each other from towns A and B which are 480 km apart. It took the first bus travelling from A to B eight hours to cover the distance and the second bus travelling from B to A, ten hours. Determine when the buses will meet after starting and at what distance from A. 


Here, distance between two towns A and B, S = 480 km 

v1 = S/8   and
 
v2 = S/10

If these buses meet after time t,  then 

S/8 x t + S/10 x t = S 

On solving, we get 

t = 40/9 hours 

Therefore, distance from A = 480/80 x 40/9 = 800/3 = 266.7 km
