Solution
distance travelled by car which started from point A from 11 am to 1 pm is = 36 ×2 = 72 km
Now it is given that total distance is 592 km
Distance left to be covered = 592 - 72 = 520 km
Speed of car started from B = 44 km/hr
Soeed of car started from A = 36km/hr
Relative speed = 80 km/hr
Time taken = 520/80 = 6.5 hours
So the two cars will meet at 7.30 pm
