$2$ tourists came at the same time from $M$ and $N$ places to meet each other, the distance between $M$ and $N$ in $33 km$. After $3$ hour and $12$ minutes distance between them reduced to $1km$, after $2$ hour and $18$ minutes First tourist's distance to cover till reaching $N$ place was $3$ times more than second tourist's distance till reaching $M$ place, find the speed of each tourist.
I've tried something like this, $v=32/3.12$ thinking it would give me average speed of both tourists then I divided it by $3$ to get the speed of first tourist but obviously got wrong numbers.
Correct answers are : $4,5km/h$ and $5,5km/h$
I've been at this problem for an hour now and still interested in how to solve this, please help.
