1. Well, let's see t' is always going to be the time of the observer who were considering
2. to be stationary for the time but will the either observe can call themselves stationary.
3. But will it can--this observer's point of view.
4. So t'=gamma*t. Well, again, y is just 1/√1-β which is 0.6²--this is 1-0.36.
5. If you carry this out, you get a gamma of 1.25 while t' is just gamma*t, t is 8 seconds--
6. then 1.25*8 is equal to 10 seconds.
7. If you got that, very good work.
