What chart is appropriate to reflect the number of cars and trucks passing through three different sections of a road at an intersection?

What chart is appropriate to reflect the number of cars and trucks passing through three different sections of a road at an intersection?

Double discount statistical chart! The traffic flow is more intuitive and the comparison is clear! I think it's it if I understand it or not!

A. The distance between the two places is 360km. Car a starts from a and goes to B for 72km per hour. 25 minutes after car a starts, car B starts from B and goes to a for 48km per hour. After the two cars meet, they continue to drive at the same speed and direction. How many hours did car a drive when the distance between the two cars is 100km?

Driving 48 kilometers per hour, how many hours does car a meet after departure?
Linear equation of one variable

Let's set out for X hours and the two cars meet
72x+48(x-25/60)=360
72x+48x-20=360
120x=380
X = 19 / 6 (3 and 1 / 6)
A: three and a half hours after a set out, the two cars met
