Problem
A rocket moving at 0.80c leaves earth towards a planet that is a distance of 24 ly from earth as measured in the earth's frame. By considering the events E1 = rocket leaves earth and E2 = rocket arrives at the planet, calculate the time it takes to get to the planet according to the rocket. (ly stands for 'light year'; it is the distance travelled by light in one year. 1 ly=c×year. )
