$0.25h and 30km$ from $A$ towards $B$

Explanation:

Motorcycle $A and B$ are $50 km$ apart.
Speed of $A=120km//h$ , towards $A$
Speed of $B=80km//h$ , towards $B$ .
Suppose they meet after time $t$
Distance traveled by $A=120xxt$
Distance traveled by $B=80xxt$
Total distance traveled by both $=120t+80t=200t$
This distance traveled must be $="Distance between the two"=50km$

Equating both
$200t=50$ , Solving for $t$
$t=50/200=0.25 h$
Distance traveled by $A=120xx0.25=30km$ , towards $B$
