You can put this solution on YOUR website!
Let +t+ = the number of minutes
before 11 AM
----------------------
+4t+%2B+30+%2B+t+=+90+
+5t+=+60+
+t+=+12+
It is 12 min before 11 AM
-------------------------
I couldn't figure this out until I drew a
" time line "

9:30 AM- - - - - - - - - - - - - - - - - - - - - - - - - - 11 AM
|<-----4t-------->|<----- 30 min---->|<--t min----->
<---------------------90 min----------------------- >
