Because of the median, AD = CD.
Because of congruence of segments being reflexive, BD = BD.
By SSS, the triangles BAD and BCD are congruent.

-(-2-5x)+(-2)=18
2+5x-2=18
5x=18
x=18/5=3.6
Shanice's rate: 93 / 1.5 = 62 miles per hour
she is 10 miles slower than twice the speed of Brandon
62 +10 = 72
72/2 = 36
Brandon is driving 36 miles per hour
