Two space shuttles are in co-linear movement, and they will collide one against the other.

If the space shuttle A is traveling with a velocity of \(0.7c\) and the space shuttle B is traveling with a velocity of \(0.8c\). If you are in Shuttle A, what is the velocity of B relative to you?

Definition: \(c\) is the speed of light.
