to be able to meet, then
A more than B to run :400-8 = 392
velocity difference as follows: 8-6 = 2
392 / 2 = 196
A: The two met after 196 seconds.

196 seconds, because the A than the B run over four laps, 400 / 8 * 4 = 200 seconds, A in B in front of 8 meters, so subtract 8 / (8-6) = 4 seconds, 200 -- 4 = 196 seconds
