Should be fairly standard suvat. The particles need to be in the same position at the same time.
Just write out the equations.

sorry, I know how to do this question, but I just confused as there are both vectors and scalars, this question is from a chapter about vectors, so I should convert scalars to vectors or convert all vectors to scalars, but I did not find any method to represent them in the same form....this is not just simple suvat.

It is two simple suvats.
Use a speed ui in the i direction and a speed uj in the j direction and solve.
If you need the scalar speed then combine ui and uj using pythagoras.

It would be helpful if you used more meaningful titles, e.g. SUVAT, vectors.

"helppppp,"
" help me in math...thank u xxx"
" help me to figure out a question please"
" help me in math"

to list the last four. They don't tell us anything about the particular area you're working in.
