Problem 1: A person leaves a place A to place B at 9 AM and reaches place B at 2 pm. Another person starts from point B at 11 AM and reaches point A at 2 PM. Find the ratio of distance covered by them at the time they meet each other?
The time gap between 9AM-2PM=5hours
The time gap between 11AM-2PM=3hours
T 5 3
S 3 5
In two hours the distance traveled by A is 6km
