Let Larry' speed be x km/h.

Then Terrel' speed is (x+2) km/h.


From the condition, you have this "time" equation


     -  = 1.


Reduce it to the standard form quadratic equation and solve it, using EITHER the quadratic formula OR factoring.


ANSWER.  Larry' speed is 52 km/h;  Terrel' speed is 54 km/h.

Solved.
