Let us suppose a spaceship moving from earth to another star that is 10ly away with a speed of 0.99c.

Calculate the of years spaceship takes to reach its destination (a) in the rest frame of an observer on Earth and (b) as perceived by a passenger on board the ship

For (a) I find that ##t_0 = x/v## which is 10.1 years. However for part (b) I am finding t as 71.6 years. However it seems wrong to me. Is it true or not ?
