The speed ratio between Party A and Party B is 72: 48 = 3: 2.
In other words, when A ran back and forth for three groups, B ran back and forth for two groups. At this time, both A and B returned to the starting point and started the cycle.
Draw the cycle as shown above in proportion, and take the distance of B running AB as the unit time.
Use an hourglass model? It is known that the second frontal encounter is (2/5) AB distance from point A..
Note: hourglass shape, with 2-4/3=2/3 at the top? , the bottom is 2- 1= 1, and the ratio is 2:3? [The second purple circle indicates this point]
A cycle, only four units, A catches up with B from behind. At this time, both of them are at point A, and the second time A catches up with B is also at point A (the time is 8 units).
So the distance between the two points mentioned in the question is (2/5) AB distance = 80m.
AB distance = 80 ÷ (2/5) = 200m.
Generally, new employees will have a probation period when they first enter the company, and the length of time varies. When they become a full member, do a debriefing report to l
