Party A and Party B practice running on the circular track. It is known that a circle of the circular track is 400 meters long, and Party B runs 6 meters per second. The speed of Party A is 1.3 times that of Party B If a starts in the same direction with B 8 meters in front of B, then after a few seconds, a will catch up with B for the first time, and set X seconds to catch up

Speed of a = 6 * (4 / 3) = 8
8X=6X+392
2X=392
x=196
196 seconds
It's a little late. The sofa's gone

As shown in the figure, a and B practice running on the circular track. It is known that a circle of the circular track is 400 meters long, and B runs 6 meters per second. A's speed is 43 times faster than B's. (1) if a and B start in the opposite direction at the same time at a distance of 8 meters on the track, how many seconds will it take for them to meet for the first time? (2) If a starts in the same direction 8 meters in front of B, how many seconds will it take for them to meet for the first time?

(1) Let a and B meet for the first time in x seconds, then 6 × 43x + 6x = 400-8, and the solution is x = 28. A: after 28 seconds, a and B meet for the first time. (2) let a and B meet for the first time in Y seconds, then 6 × 43y = 6y + 400-8, and the solution is y = 196. A: after 196 seconds, a and B meet for the first time

1) If Party A and Party B start in the opposite direction 8 meters apart on the runway at the same time, how many seconds will it take for them to meet for the first time? Kkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkkk

(400-8) / (6 + 6 * 4 / 3) = 28 (seconds)
A's speed is 6 * 4 / 3 = 8 m / s, and a and B run 400-8 = 392m when they meet. The sum of a and B's speed is 6 + 8 = 14 m / s, so a and B need 392 / 14 = 28 s when they meet
