Description:
Car travel from X to Y (4 hr)
Bus travel from Y to X (6 hr)
Time taken to meet = time taken for both distance travelled to reach from X to Y
To calculate time required,
We check ratio of the distance travelled per hour.
Knowing an hour the ratio travelled,
We can find the time needed to travel the entire distance,
From there, plug it into time start (1130) and find the time they meet //
