alright,i'm a little drunk now,but i can still answer your question:
internal total reflection condition:
n1sin p=n2 sin pi/2 ===> sin p=0.98639455782312925170068027210884
total time = (L/sin p) /(c/n2) =(1000/0.98639455782312925170068027210884)/(299792458/1.45)=4.9033921994128363799714010012292e-6
