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?
1 microsecond is 1 millionth of a second
1 second is 1/60 minute
1 microsecond =(1/(1,000,000))(1/60) of a minute
1 microsecond is (1/60,000,000) of a minute or
1 minute=60,000,000 microseconds
4 minutes =240,000,000 microseconds
We know that (instructions/microsecond (36))times(total number of microseconds (240,000,000) = total # of instructions
So in 4 minutes the computer can execute 36(240,000,000) instructions=
8,640,000,000 instructions and this equals (8.64)(10^9) instructions in 4 minutes
Hope this helps---ptaylor
