First MJ is in RI not NY. I belive that central city is in Missouri. So he got from RI to Missouri in about the time it took Nightwing to call Wally Barry and maybe whoever is in the current head of the JL. As for the Wally part, he did show up maybe a min or two after Bart got there and Wally came from North Cal.
