How do most students in puerto rico go to school? a. they walk b. they ride a bike c. they take a school bus d. they drive their own car

They walk

Cause many students, parents, family cant afford the money to go on buses, bikes, or cars. Either school buses cause who knows if the school buses stop where they live

I hope this works

YW!
