Jose is looking to the east. Lightning bolt 1 strikes a tree 300 m from him. Lightning bolt 2 strikes a barn 900 m from him in the same direction. Jose sees the tree strike 1.0 microseconds before he sees the barn strike. According to Jose, were the lightning strikes simulataneous? If not, which occured first and what was the time difference between the two?
