1. The problem statement, all variables and given/known data
You fly 5000 km across the United States on an airliner at 250 m/s. You return two days later traveling at the same speed. How much less have you aged more then your friends at home.

2. Relevant equations

I think the time dilation equation is used:
delta_t= delta_t'/ sqrt(1-beta^2) where beta= v/c

3. The attempt at a solution

I have the solution from the solution manual but i'd like to know how they got to the answer, 1.39×10−8 s.

to find the delta t is the equation delta_t=delta_x/v used?

the beta is (250m/s)/(3.0*10^(8) m/s )

i keep getting 1.7 *10^-5 although the solution manual says this is incorrect.

hi !

I've been so desperate to find the solution manual for mastering physics..!

Can you please tell me where you got it/?

or if it is possible, I would really really appreciate it if you could can it to my email, which is
