80 × 3-60 = 180m

Car a travels 40 kilometers per hour, while car B travels 60 kilometers per hour. The two cars start from a and B at the same time and travel in opposite directions. Q: after the two cars meet, they drive to B
Car a travels 40 kilometers per hour, while car B travels 60 kilometers per hour. The two cars start from a and B at the same time and face each other. Q: after the two cars meet, how much time does it take for car a to reach B than for car B to reach a?

2.25 times
If the time of meeting is m, then the distance of a meeting is 40m and that of B meeting is 60m
After meeting, the time from a to B was 60m / 40. The time from B to a was 40m / 60
（60m/40）/(40/60m）=9/4=2.25
