Heat Transfer Equation

Hello, i am new to MathCad and how could i solve this equation in MathCad. 

These are the boundary conditions

• 

  on the left bound

• 

  ; on the right bound

• 

Initial condition is T(x,0)=300K

Obtain temperature distribution on each moment of time and each  point of the dimension space(t0=0, tf=150 sec).

I have no idea how to do it in MathCad. Sorry for the inconvenience caused
