Two motor boats A and B move from same point along a circle of radius 10 m in still water. The boats are so designed that they can move only with constant speeds. The boats A and B take 16 and 8 sec respectively to complete one circle in stationary water. Now water starts flowing at `t=0` with a speed `4(m)/(s)` in a fixed direction. Find the distance between the boats after `t=8` sec.

A

`(1)/(6)m`

B

`(1)/(3)m`

C

25 cm

D

50 cm
