Two people are $16$ km apart on a straight road. They start walking at the same time. If they walk towards each other with different speeds, they will meet in $2$ hours. Had they walked in the same direction with same speeds as before, they would have met in $8$ hours. Find their walking speeds.

Let walking speeds be $x$ km/hr. and $y$ km/hr. $(x > y)$
ATQ, $2x + 2y = 16$
and $8x - 8y = 16$
Solving to get $x = 5, y = 3$
Speeds are $5$ km/hr. $3$ km/hr.
