You can put this solution on YOUR website! A computer can execute 36 instructions per microsecond. How many instructions can it execute in 4 min?
-----------------------
(36ins/1 microsec)(10^6 microsec/1sec)(60 sec/1 min)(4/4)
= (36*10^6*60*4ins)/(1*1*1*4min)
= 8640 million instructions/4 min
= 8.640*10^9 instructions/4 minutes
