A) How fast is Anna's spaceship moving?

v/c = 0.781

B) What will Anna's clock read when she sees the tail of her spaceship at the doorway where Bob Jr. is standing?

1.04 x 10^-7 s

C) How far will Anna say the front of her spaceship is from Bob at this time?

24.375 m

I'm extremely confused. I know d = vt. Then, t = d/v but v is not given and I was thinking about using c, 3 x 10^8 m/s. Any help is greatly appreciated, thank you
