As measured on Earth the star Fomalhaut is 25.1 light years away. As measured by the crew of a spaceship that flies to Fomalhaut, the distance is 7.1 light years. In years, calculate the duration of the trip as measured by the crew of the ship. (Give your answer in years but don't include the units.)

Frame of reference

In physics, a frame of reference is a coordinate system used to specify either the position or the orientation or velocity of a body. The origin of the coordinate acts as a reference point for measuring the position or relative motion of a body. The coordinate system can be a cartesian coordinate, cylindrical coordinate, or a polar coordinate.
