I have a question regarding the following picture:

Here, person B is moving in his

**S’**reference frame with a speed of

*relative to Person A, who is in his reference frame*

**u****S**. An event shown by a star (*) happens after

**t**time according to A.

_{A}The distance of that event is a distance of

*x**according to Person A*. The distance of that event is a distance of

*x’**according to Person B*. From this we can relate

*and*

**x’****by using the Lorentz length contraction formula.**

*x*Person A will calculate that his own distance

**is equal to:**

*x*Here’s my question; what is the relationship between

*and*

**x’**

*x**according to Person B*in a formula in which person B uses his own time

**t**? So I’d want to relate x, x’ and

_{B}**t**in a formula. How do you do that by concluding it

_{B}*from the picture*instead of rewriting my given formula for Person A?
