the radius of a circle is 11m.......A,B and C start moving from a point at same time in a circle....A and B clocwise....C anticlocwise.....if A meets C in 88secs.....B meets C in 110 secs.....in what time will A meet B?????? Pls show the steps!!!!

22∏/(Va+Vc)=88 -----(1),

22∏/(Vb+Vc)=110-----(2)

so from (1) and (2)

Va-Vb= ∏/(20)----(3)

 

lethe velocity of A with respect to B is Va-Vb i.e. B is stationary and only A starts moving with the velocity Va-Vb. so time taken for meeting again is

22∏/(Va-Vb)=440 sec.
