Captain Kirk is chasing a Gorn and sees the Gorn will reach safety in 250m, as measured from Kirk's location. Kirk is running at 5 m/s while the Gorn is running at 4 m/s and the Gorn has a 90m head start. Scotty brings the transporter back online and can transport Kirk instantly to catch the Gorn. How far must Kirk be transported to catch the Gorn before it reaches safety? Assume the transport is instant.

Relative Velocity

It is a measurement of an object with regards to the other object which is moving or stable or stationary. For example, if we are traveling in a bus and the bus is moving at speed of 50km/hr, then our speed is according to the nearby passenger on the bus is zero. According to them, we are not moving. But if one person standing on the ground or road observes us from outside of the bus, according to him we are moving at a speed of 50km/hr and the bus is also moving at a speed of 50km/hr. Now, the motion is recognized by the observer, it depends on a frame of reference or observer. This is motion called relative motion.
