Reach the astronaut as gauged on the astronauts clock

Reference no: EM13667618

An astronaut is traveling to the Moon at a speed of 0.57c. When his spacecraft is1.9*10 8 m from the Moon, there is an explosion on the Moon. How long does it take for light from the explosion to reach the astronaut as gauged on the astronaut's clock?
